1995 F35 smokes on excerleration

Check the oil level. Is it over-filled? White smoke usually means oil burning off somewhere. Not sure how to answer your fuel guage issue.

C-

 

If your overfilled with oil the it will draw into the intake manifold resulting in your smoke cloud, this will also damage the head gasket if not addressed quickly.

 

White smoke is generally water/antifreeze burning in the combustion chambers. Head gasket leaking.
Compression check may still yield good numbers at cranking speed. Check you coolant level and
monitor it. Blue smoke = oil burning

 

I don't see an O2 sensor causing the car to smoke....

 

Your posts seem a little confusing/contradictory. Do you get the smoke under acceleration -- i.e., large throttle opening under heavy load with RPM increasing (which is how you titled the thread) or deceleration -- i.e., closed throttle at high falling RPM under no load (which is what you just described)?

 

Sorry for a minor hijack, but for lawnmowers, I had his problem..overfilling it with oil or something, it causes white smoke, with a very small blue tint. Is this the same thing?

 

355? Worn valve guides....common problem for pre '97 models...check it out......What year model is yours?

 

If it was a head gasket leaking antifreeze it would do it at idle as well. I go with the valve guide issue.

 

Ok, that's more clear. If the valve guide wears significantly (so the physical clearance between the valve stem OD and the valve guide ID becomes large), this can allow oil to be sucked into the combustion chamber under heavy engine deceleration (because the vacuum inside the cylinder goes very high during the intake stroke since the throttle is closed). Initially, it doesn't show up as a performance problem because the valve head can still be sealing fairly well on the valve seat; however, once the valve guide wear gets really excessive, the valve head (being off-axis from the seat due to the valve guide wear) will "crash" into the valve seat during the closing action and damage itself, or the seat, enough that it will hurt performance and/or be detectable as bad compression or bad leakdown (or the valve head may break off and cause even more damage).

As has already been mentioned, you need to ensure that some other factor isn't causing oil (being overfull) or coolant (a head gasket leak) to get into the combustion chamber, but once you've ruled those out, there isn't much else to blame except the valve guides. Try a search on "355 valve guide wear" -- should get you a lot of prior discussion/explanation.

 

Even in Tejas, "accelerate" is only pronounced "excelerate"...

 

Jake,

Is Steve Smith looking at your car? He has done a ton of '95 355 valve guides. It was a known problem up through '97 or '98. I believe there was a recall on it back then. If Steve is working on it, tell him I said hello. I worked at FoD with him for 3 years, both at the old location on 75 in Richardson and the new store in Plano. Tell Danny in parts he needs to get to work and tell him I said so..............

 

That is the normal method. No need to trial and error it if they can identify it exactly. My bet is on the valve guides knowing the history of them........hope it turns out well for you....

 

Steve is no longer employed at Boardwalk, Danny is still here, though.

 

Where did Steve go? I know Mike is at Lambo but I have not been to Boardwalk in a while so I am behind on keeping up with them.

 

While there you might have them check out the exhaust manifolds. They had huge problems with the '95 355 ones and replaced many of them. It would have nothing to do with your white smoke issue but it is something to watch. They may have been replaced by a previous owner before you go it.

 

Hope it works out to be the cheaper. I dont know of a better tech than Micheal L.

 

Steve went north to play with race cars, Mike works with us on our Challenge team, and we have some pretty good techs to keep those poni- no, that's James' line - we do pretty good...

 

Both Steve Smith and Mike Luongo were great Challenge techs while with FoD. FoH/FoD had a very, very strong team during that time..........Doc Earle, Kevin Crowder, Bill Rand, Paul Frame and a whole host of others at the same time. Those were the daysss...
