Bad fuel air mix. Throttle body out of ajustment or injector damaged during reinstall or computer getting wrong info. Or they did not machine the heads before they put them in.
cracked heads, water and oil are mixing
you may have a blown head gasket. if you keep driving on a car with A BLOWN HEAD GASKET it may permanently damage your engine (especially if you have aluminum heads-they'll worp). if the heads are shot, it's all over. you need to take it to a shop and have it looked at. if that is the problem and they can replace the gaskets without damage to the heads, it won't be cheap. it's a tough job.
They can if the heads are cracked ,are the intake manifold gaskets were put on wrong when thay were installed. The heads themselves if thay are good heads will not cause overheating. You cannot put the head gaskets on wrong on a small block Chevy engine.
Steam from the tailpipe, and water in the oil means you have a faulty head gasket. Not a good thing. The steam is the antifreeze/water coolant leaking into the heads (bad gasket) getting heated by the engine and coming out as steam. The water in the oil is the same deal, but it;s collecting in the oil so it isn't coming out of the tailpipe. You need a new head gasket. I promise.
On the very top of the engine there is a intake manifold and the intake gaskets go between the intake and cylinder heads.
The heads don't necessarily need to be resurfaced when you change the head gaskets unless you think they may be cracked. They should be resurfaced every time the gaskets are changed, but you can get by without resurfacing them.
you will probably need to change heads gaskets
Not on the head gaskets.
Sandwiched between the heads and the engine block.
The 283 has a larger bore diameter, so use the 283 head gaskets.
From 1996 to late 1999 There was a problem with the intake gasket design on the Vortec engines. They have sents redesigned the gasket and now it does not leak as often. Intake Gaskets leaking is a common problem. Now the only time you have a problem with the heads is when the engine is over heated, and I mean HOT. Then the heads warp and the head gaskets leak or blow. Chevy just don't have problems with the heads on the V6 and V8 engines.
could be a faulty thermostat don't over heat it to often you'll end up blowing your heads gaskets drive safe
The iron heads leak due to the expansion and contractions of the meterals that are difrent at difrent temp
You have a blown head gasket. Remove the heads and replace the gaskets. Also have the heads inspected for cracks.
Remove carburator then intake manifold then cylinder heads
yes just get head gaskets for the 350 not the 327
Removing the head(s) and having the heads reconditioned, installing the rebuilt heads with new gaskets.
Sift heads 6 is already out.
Depends if the heads are cracked or not. Typically $50+ for the gaskets (intake & head)... $200 if you ned the heads reconditioned... $60 if you need the heads resurfaced only... More if you need a replacement for a cracked head... Plus labor to R&R the intake & heads, readjust valves, add coolant, set timing, etc.
Thick white smoke is an indication of coolant entering the combustion chamber. More than likely you have a blown head gasket, especially if the engine has overheated recently. Stop driving this car as severe engine damage will occur due to coolant in the oil. The heads must be removed and new head gaskets installed. A major repair.
Then the heads must be removed and inspected for cracks or warpage, and new gaskets installed.
There are two head gaskets,one for each head.
Overheating can warp and crack cylinder heads, head gaskets and all bearings, especially crank bearings. In extreme it will destroy the engine
The heads are aluminum, the block is iron.
Heads do not have to be ground because they are aluminum. If you're taking both heads off then you need 2 new gaskets. It's not a bad Idea to replace both if one is leaking though because the other one might not be far behind.
