Need some help guys.

Have a possible blown head gasket or cracked head. Looking to try and get some input from you.

Car has been modded with a smaller 3.5 pulley, CAI, Thermostas, PCM tune. Been running fantastic for over a year. 2002 with 140k on it.

LIM gaskets were changed when I bought the car.
Drove the care yesterday cold, romped on it and got an error code "service engine", loss of power, engine shut down. Throttle response was very delayed before loss of power. Upon restart white smoke out of exhaust. Coolant blown in engine bay.

Stripped it down and replaced all the LIM and UIM gaskets. Found coolant in the oil.

Did it by the book.

LIM gasket was found to be destroyed on supercharger side on engine.
Put everything back together, everything flushed twice with fresh oil. Coolant added and topped off. Started her up and let her run for about 2min Pressure in radiator, with cap off it gurgled and spat out coolant.

Still has white smoke out exhaust. Ran a bit rough. Possibly on 4 cylinders. No error codes were given like before. Looking for advice.


Thank you.
Macson

Well first thing... Why are you romping on a cold car?

If a lot of coolant got into the combustion chambers and exhaust it may take a little bit for it all to burn off. Maybe your plugs have become fouled? I'd double check over the ignition system and all of the sensors.

Head gaskets are super solid on these motors and unless it overheated, I'd doubt that would be the issue.

^^^^ Well you are exactly right regarding the intelligence level of what I did. Lol.

How long should it take to burn off? Now that I have daylight available I will double check everything just to be sure.

From the LIM jobs I've done, everything that would be going through the exhaust should be burnt off in a few minutes. Anything spilled in the engine bay might take a few heat cycles to fully burn off, but if you don't have any more leaks, you should have clear exhaust fairly quickly I would imagine.

That is what I was expecting. Looking more and more like either a failed gasket or worse even a cracked head. Time to get my hands dirty and take her apart again digging deeper this time. Going to double check a few things first but I have exhaust pressure in my radiator so I am pretty certain its a head issue.

you can start the car with all full and cap rad - if you have head damage, gas will be forced into the cooling system and you will see the bubbles forces into the overflow.

or better is a compression and balance test

you sure you put everything back correctly?

I would definitely do a leak down test before you tear into things to verify that it truly is exhaust gas in the coolant. If there is exhaust coming in for sure, then you may be one of the rare few that has a head/head gasket issue. Hopefully that's not the case, and maybe it was just a slipped gasket or something simple during installation.

Did the test today. Test Fluid turned yellow almost instantly when gas sample was taken from the radiator. Pressure was pretty violent. Had to run the car briefly then shut off. Relieve pressure from rad cap and quickly use the test kit. Couldn't run the car with rad cap off. It was just shooting coolant 3ft in the air.

Guess I am one of the rare few. Already started tearing into her again. Smh. Time for a header upgrade anyway.

Sorry to hear that man! Post up some pics of what you find if you don't mind. Always interested in seeing what caused failures like this when they aren't as common.

boo, thats tough - at least your mechanically inclined so look at it as an adventure.

plus, when you're successful, you will be envied by other men and pursued by chicks.......lol

Been tinkering away getting her apart. Just removed the rockers last. Had to stop for work. Should find the source of the problem over the weekend.

What the He!! I will put the speed daddy headers in while I have her apart.

QUESTION FOR YOU GUYS:
When torquing the lower intake manifold back in place. I understand factory torque is between 13-14ft lbs. I will be installing the 2nd Gen Felcro gaskets. Should I or can I do anything else to help prevent a LIM gasket failure in the future?

as far as I understand, the metal edged gaskets solve the problem caused by plastic original ones.

Yep! I used OEM GM metal-framed gaskets on my Buick, and it was still going strong with over 60,000 miles on the new gaskets when I sold the car. Otherwise, make sure that you get the end seals set correctly, the the metal coolant elbows instead of the plastic junk ones, and it should be solid. As long as I've been on this forum, I don't recall anyone having the metal framed gaskets fail on them unless something else in the engine wrecked them first (big debris in the coolant, etc).

Ok. So Front Head is off. Rear will also be replaced but the front gasket was the culprit. Looks like the cylinder #1 had a slow leak for some time as it was the only cylinder with build up on it.

*edit. If you can't see photos let me know which provider to use other then photo bucket.
