Not burning oil before 19 years of sitting, now it is?

The cooling fins on the cylinder head and the cylinder block, will heat up fairly quickly, as they are in direct contact with the combustion process..........................
The engine oil on the other hand, will take quite some time to heat up to operating temperature..........
On cool mornings, the oil in my FJ engine will sometimes take my whole commute (approx 25 minutes of in town, stop-and-go riding) before it reaches operating temperature......(190-200 degrees F)

More than likely, this is what you are experiencing when you start the engine and put your hand directly on the engine cooling fins, and then put your hand on the oil cooler..........The oil is probably not up to temperature yet.

The oil cooler is not on the main engine oil pump circuit.  The pump for the oil cooler just circulates oil between the cooler and the oil pan.

So Mr. firebird of prey, ;) that's what I was kind of thinking, I thought that it may even be under some kind of thermostat control in the pump.

Actually it's not just the cooling fins that I was talking about, obviously I knew that the metal around the combustion chamber would be the hottest, as well as the headers, been burnt many times due to complacency,  :dash2:, but other parts get hotter than the oil cooler as well, like the cover for the "pickup coil governor" which really surprised me, because it's below the combustion chamber, adjacent to the sump.

In the end I think I'm just being way too paranoid.  I really just don't want to frack this up right about now, it's just way to important to my wife's an my welfare, as our only running vehicle.

I made some important headway today, and ended up finally riding her around the block a couple times.  There are still a few kinks to iron out though, before she's safe to ride, some of which I plan on taking care of tomorrow.

Wow, I had no idea there were two mechanical pumps in the engine.  I'm assuming that you've been inside the engine and done some work.  Thanks for the info, Hooli, the mental picture of my bike keeps getting clearer and clearer.

Thanks to all you guys that take the time to help the "nervous mechanic," (me).  I'm just feeling old and incompetent due to all the pressure we're currently experiencing, but she's gonna change all that...

...I just hope I don't kill myself in the process, I think the wife actually needs me sometimes!  :yes:  :sarcastic:

Congrats JoBro! Progress my man, getn that first ride after19yrs...epic,simply epic! I bet the memories are flooding you're brain into Maximum-Overdrive about now!    Lotsa work but well worth the effort right? Dam about your car if you were closer I'd let you borrow one. Well, press on, gonna jam today with my childhood friend awesome keyboardist then go for a ride.  (Hes got a sweet Bumble bee '76 CB750F) Maybe we'll try Red Barchetta...my Whisky/cigarette voice I'm no Geddy!                 Charley.

A touch of the Prog Rock band Marillion maybe?

To say the least, I was elated, overjoyed, soaring high on the Silent Wings of Freedom, something inside, flying even higher still, almost to the Dark Side of the Moon, for I have dined on honeydew, and drunk the milk of paradise; she giving me emotional feedback on a timeless wavelength, bearing a gift beyond price, almost free.

Yes Charlie, it felt great, my trusty steed with its stock airbox and mufflers humming, with that familiar slight whistle, but trust me it's not even close to over yet.  Not only am I going to continue tuning, but I have tons of cosmetic things to do, as well as general maintenance, replacing as much of the rubber as possible, etc, etc, etc, ad infinitum.  What a wild ride it's gonna be!  Sorry, didn't I tell you?  I was Born to be Wild!

Yes, Maximum Overdrive, or maybe pushing for that Mind Drive.

Thanks for the friendly exuberance, at my inkling of success, it's much appreciated, a little bit of icing on the cake, to share the joy of riding the astral plane, trips around the bay, to be back the same day! No! Not Timothy Leary! ;)

I hope you and you childhood friend had fun pickin' and a grinin', a strumming, and a tickling those ebonies and ivories, those flats and sharps be just as important, depending upon the key. ;)

Later my fellow FJ'er and Guitar aficionado!

Had a great afternoon riding with Jimmy. Lotsa killer roads nearby, only wish I could ride em year round. Didnt have time for  playin music...but it didnt matter! Hows the oil burning issue? Hope fully it'll loosen up and fix itself...might help to pray to the Gods of Internal Combustion. Hang it there man!  Heres a pic of Jim and CB-F.                                        Charley.

Nice bikes, especially the red and white one, it somehow looks familiar. ;)  :lol:

Not really burning oil, but it is dripping from the oil filter, (flattened O-rings), onto the exhaust, 4 into two, collector, and smoking from there.  The new O-rings arrive tomorrow.  I also purchased a head gasket and 8 of the head bolt rubber plugs from RPM.  It is leaking slightly around #1 & 2 cylinders. While the cover is off, I'll finally do the valve adjustment, as the valve tool is coming soon as well.

I am having another problem though.  After it gets hot after running for a while, the Idle raises slightly, and is hard to adjust to 1k.  It seams like possibly a vacuum leak, but if so, I don't know where it's at.  Someone said earlier that with heat, it sounds like some hole/crack is expanding, thus changing the A/F ratio.  I have not changed either the intake manifold boots nor their o-rings yet.  They seem sound though, because I've sprayed WD-40 around them, without an increase in idle speed, though it may not have been hot enough yet.  It is frustrating. In time I guess.  Unless someone has any ideas as to specific more likely causes/checks to perform so as to exclude possibilities, and narrow it down.

Alright everyone!  If anyone has any ideas, I'm all ears!

A idling condition that increases as the engine gets warm, can mean that your idle mixture screws are set too rich.

Try leaning them out (turn in) 1/4 turn to see if that helps.

Thanks Pat, I am having a problem setting them, and have temporarily set them all to 3 turns out.  Of course as to my knowing what I'm doing, Randy's recent explanation as to the primary circuit, i.e., pilot jet, bleed air jet and mixture screw, has left me with more questions than it does answers.  Not that I don't understand what he's saying, I do, but I really don't see that the orifice that the mixture screw opens is necessarily a constant either, which the thumb nail ensuring an initial flush setting, assumes.  I used to be a machinist for a short time and know how different parts with different tolerances come off the line.  The problem he mentioned deals with the screw holes depth, the tapping process allowing the screw to reach varying depths, but one has to consider diameter as well, which also varies from part to part, not the screw hole, but the one the screw is opening/closing to vary the quantity of fuel/air.

I'm seriously considering buying a ColorTune device, or is that actually a ColourTune, seeing as how it's British, I say there old chap, cheerio!  :biggrin:

Thanks again, I'll fiddle with it in small increments tomorrow.

I just love this food for thoughts you guys dish up!  ;)

You really need to stop over thinking everything.  A lot of the advice on here comes from decades of experience with these motorcycles.

It's okay to question the advice.  But to continue to question EVERYTHING is getting a little tiresome.  Try some of the recommendations and see if it works before you over analyze it to death.  Asking a question then disagreeing with someone's "solicited" opinion by siting some internet search results makes me wonder why you even ask the question. 

Sometimes we might not be able to explain why the universe spins in the direction that it does.  That doesn't mean that our firsthand experiences are necessarily invalid just because it doesn't agree with your preconceived notion or something someone else wrote on the internet.

BTW, the Colortune is worthless.  The blip test is far more accurate.  But go ahead and spend your money

You do realize that you are asking me to stop being me, right?  What if I asked you to stop being you?  Would that offend you?  There are things you don't know about me, that are why I am as I am, that you probably wouldn't want to hear.  Hooli, either you can tolerate me or not.  I've really valued your giving me time, truly I have, but you can always ignore me if I'm that much of a bother.  No I'm not being ungrateful, just don't like feeling bad about myself, I've had enough of that during the first 17 years of my life.  I have no time for people attempting to make me feel guilty for being me.

No hooli it's all about sequence, my friend.  I didn't set anyone up, with knowledge I already had, then asking them the question just to slap them in the face with that which I already knew, not at all.  I'm actually a pretty smart guy, according to my IQ tests.  When I hear someone use words that I know the meaning of, and they are contradictory, I seek other avenues, then I either find the same info, or conflicting info, and in either case I believe it's important to relay that info back to those that seem to have it wrong, I feel that I owe them that much!  To me it's not about who is right or wrong, rather all that matters is the truth of the day.  I'm not here to compete, rather only to find the truth.

I agree, and that applies to everyone just the same!  Some people, at any particular time in their life, seem to be more adept at recognizing the truth when it presents, at other times they're not.  For instance, I believe I may have found the reason for the petcock SNAFU, that causes the pressed in fitting to fall out, sending fuel all over the engine, potentially making the rider Johnny Torch.  So far I've not seen anyone present a potential why of it happening.  Of course I could be wrong, as I haven't verified it yet! Which is why I haven't said anything.

Cool, am I to understand that you've actually had an experience with one of them?  If so, what specifically did you find as it's problem?  The reason I have a problem with the blip test is that it can't differentiate between the cylinders; there is no indication of which cylinder requires tweaking, so it's a guessing game of hit and miss. So one can easily screw up a cyl that was perfect, only to find out much later with continued fiddling. The colortune, on the other hand, allows one to see exactly which cylinder is richer or leaner, all one has to do is place it in every cylinder, one at a time, then they're done, "from Yellow, to just Blue" is perfect, so they say. That is if what they say is true.  I've watched a youtube video that surely seems to verify their claim.

I'm not pissed, you have your opinion and I have mine.

I think I acquired one of those setups with the purchase of an MG a while back. Haven't had the time to try it out. One day...

While I admire your quest for perfection and the truth, I also wonder how you sleep at night.  Being the father of 3 teenagers is more than enough for me to worry about.

You don't need a full error budget of the idle mixture circuit tolerances to know what works for adjusting it.  Is it perfect?  No!  But this isn't brain surgery. 

For the Colortune, I have not personally used one but based on the opinion of people that I trust I decided that they aren't worth it.  Maybe they redesigned them but the original ones were very hard to read.  It had to be at night with the lights out in order to see the flame.  If it gets me 100% perfect it's probably still not worth the cost or effort to me when I can get ~98% there with the blip test.

I once paid a dealer to set my mixture screws using an exhaust gas analyzer.  That should have been perfection.  Unfortunately it was just a waste of $50.  Motor surged and stumbled at low throttle.  Went straight home and readjusted them to what works in the real world. 

For the petcock, what caused mine to come apart was the pulling and twisting to remove the fuel hose.  That eventually loosened the outlet pipe enough to where it would fall out.
