8172, 94 ply laser 2.0 smoking badly
Posted by jap901, Jun-20-05 02:46 PM
Hello I purchesed this car cheap to fix for my wife. When you crank the engine up it does not smoke untell it warms up and it is very little but it you step on the gas it realy starts rolling out the smoke so i am thinking the head needs rebuilt but what do you all think?

The engine has 164000 miles on it so I am thinking of rebuilding the hole thing, I am not wanting to build it for high H/P but for gas milage.

What items/mods can help increase Milage?

Thanks Jim

I am assuming it is a non-turbo? What color is the smoke?

It is A none turbo model and the smoke looks white to me but i can smell the oil. I was just going to rebuild the hole thing because it has 164000 on it but i am going to pull a compression test on it and see how good the bottom end is b4 i deside on a complete rebuild.

the car been setting for about a year and a half because the trans is slipping and it didn't smoke when it was parked but does now, so by what i have been reading i think it may be the valve seals.

Thanks Jim

Hello, I did a compression test today and the engine has 190psi on all 4 cyl, so I am still lost to as what is cousing this. It does not smoke a lick till it warms up.

Valve seals normally leak at start up, then clear up as the car runs. The seals go soft and leak oil into the cylinder when the engine is off, they generally don't leak alot when the car is running, but it is possible. Your problem could be something as simple as a pcv valve, but smoke comeing from the dipstick tube sounds like blow by to me, even though your compression is good you still should not have smoke coming from your dipstick tube. IMO I'd re-ring it with a new head gasket.

I was told to do a wet test do to the compression rings can be good and the oil ring be bad.

wet test # are 1=240psi 2=220 3=240 4=210 turn engine over 4 times

Wet test # 1=270 2=240 3=260 4=230 turning engine over till needle holds steady

The dry compression test # 190psi on all for turning engine over 4 times.

dry compression test 1=210 2=200 3=210 4=210 turning engine over till needle is holding steady.

This is the how to page i went by to do compression test: http://www.dsmgrrrl.com/FAQs/compression.htm

Thanks for your input and replys

update I had my father in law look at the car and he told me to rev it up and let off the gas and this was done b4 it was warmed up and it woud spit out small puff of smoke. he seems to thank its the valve seals he said when you rev it up it bulds up a vacum and pulls the oil though the valve seals.

Does this sound about right?
