I have no idea what you just said. All I got was 86 Deville, 4100, exhaust pipe. If we're going to help try using punctuation marks and proper spelling.

i have a 1986 cadillac deville and i am having trouble there is white smoke comin out of my exuast pipes and i dunno what needs to be replaced or what the problem is its drivin me crazy

Are there any other symptoms? Check trouble codes - press OFF and WARMER buttons simultaneously on the climate control (key on), then write down any letter/number codes that appear in the Fuel Data Center. Post the results and we can go from there.

the codes that are coming up are e-22,31,34,52,53,55,63

Sounds like you need a new MAP sensor to start. Check the wires and vacuum hoses to it first though. 53 is distributor signal interrupt... That's a combination that will surely make the car run like utter crap.

Check out the MAP sensor and your ignition system first... There still shouldn't be white smoke though. That's either antifreeze or steam burning off. It's possible that's intake manifold or head gaskets...but get those other two issues in check first before panicking lol.

That's quite an array of codes, but I agree with Tailfin, it sounds like the source is the MAP sensor, which then compounded into all the others.

Regarding the smoke - check your oil. If it looks like Cream of Mushroom soup, there may be coolant getting past the intake or head gaskets. Is your coolant level dropping, but you're not noticing any in the driveway?

Have you ever changed the coolant and added the GM sealant?

Yeah, white smoke definately isn't good. If you wanna be technical that's mostly steam coming out. Check the oil for signs of coolant like noahsdad said, also give the engine a good inspection for coolant leaks before doing anything else. It would suck to start spending money on new sensors and crap and then you find out it has a blown head gasket.

Actually, white smoke and poor engine performance sounds more like way too much fuel.....as in stuck or leaking injector. A stuck fuel injector will cause white smoke due to very rich operation. Normally, the assumption is that "rich" causes black smoke. As long as it is not too rich to run then that is true but a flooding condition that causes severe misfire will cause white smoke.

You have too many codes. Check the battery cables, connections, grounds.

well i took it to like 4 or 3 shops and they all told me that im gonna end up rebuilding the engine or gettin a new engine to put in it so i dunno cause it defently gots a misfire in it and the exuast is just puffin a bunch of white smoke out and u know i got chrome wheels and chrome dual exuast tips and it looks good and everything but mechanicaly its very poor and stuff

my motor has like 161,000 on it

Replacing an engine just because an injector leaks????? Take it to a shop you TRUST and ask them to inspect injectors. It is not difficult at all. Or let us know you you are willing to do it yourself. Did you check the battery cables/contacts/grounds?

yeah i checked it

Hi Brandon,

If you have white smoke coming from your exuast pipe the only thing that will cause white smoke is engine coolant. It may entering the combustion chamber through a faulty head gasket or a cracked cylinder head. You may have to have a shop pressure check the cooling system.

White smoke comes from bad oil rings(oil leaks past the rings into the combustion chamber) or bad valve guides. If the smoke is only present at start up then it is valve guides and can be replaced without tearing your engine apart. But, if white smoke is present all the time then most likely your oil rings are bad. The misfire can be caused by a number of things such as faulty ignition wires, bad fuel injectors (too much fuel cause black smoke from your exhaust), or damaged, burned valves, but I think in your case you may have some bad compression rings. The other thing that might cause white smoke is coolant leaking into the cylinders. This is not smoke it is steam which comes from hot engine cylinders and exhaust system. This meens you have a blown head gasket or cracked cylinder head, if this is the case you may have coolant leaking into the cylinder or cylinders and can cause serious damage to the cylinder walls. Get it fixed as soon as possible to avoid such an event. I hope this helps you with your problem. I have a B.A. in Industry Technology with emphasis in automotive technology.

I have an 86 Cadillac Coupe DeVille that has 96,000 miles on it and is in perfect working order. It has never had a hard day of driving ever. I am the 3rd owner the other 2 were my grandfather and my mother.

If you need injectors The 4.1 's are simple to replace easy to get at
If you need help with it I can get you info I tend to agree that your head gasket could be causing coolant to burn in the combustion chamber and cause the white smoke.

You've got a blown head gasket.

The caddy motors with aluminum blocks and cast iron cylinder heads are notorious for this. The reason is the block expands 10 time the amount the heads do.

Why do you think they need coolant sealant right from the factory?

It is to correct a very poor design.

It is to correct a very poor design.

That's inaccurate. Mixed metal engines have been around since World War II, and they all experience gasket sealing issues. Every manufacturer of aluminum block engines deals with this same problem - they just go about it in different ways. Cadillac merely chose a method that is renewable on a regular basis. If the owner reads the manual and follows the schedule, the failure rate is comparatively low.

But back to the thread. My experience has been that as soon as a mechanic opens the hood and sees HT-4100, they start talking major overhaul. The 4100 had problems no doubt, but some of that reputation is caused by hack wrench benders who don't know how to diagnose or repair them.

Brandonbyrd - have you done any of the steps suggested here to see for yourself where you stand?

The engine was notorious for two things -- intake or exhaust manifold seals destroying the engine and soft camshafts. If the oill looks like chocolate milk its the seals. If its the camshaft it gives out around 135,000 - repower the car.

When you get a string of codes it's the ECM. The computers never tell on themselves. A new ECM / remanufactured is only about $120. AT aDVANCE aUTO pARTS.

I have both the GM Body service and chassis manual if you want it let's deal.

It will make you an expert.

I will soon be the proud owner of a '84 with the 4100 engine that has 65,000 miles on it. I just might need the manuals, so what are you asking for them.
