1. disconnect battery & drain coolant
2. remove distributor, fuel injection, upper hose, misc cables & wires on top of intake manifold.
3. remove brackets that mount to intake manifold, remove valve covers.
4. remove intake manifold
5. remove spark plugs, remove exhaust manifolds
6. remove rocker arms & pushrods.
7. remove head bolts, remove heads.
8. clean & inspect block deck surface, inspect piston tops and cylinder walls, clean head bolt threads.
9. you should have heads reconditioned, and definitely resurface them.
10. install new head gaskets (right side up), put sealant on head bolt threads, install head bolts.
11. torque down head bolts in proper sequence to 60-65 ft lbs.
12. clean & install rocker arms, balls, pushrods & nuts.
13. Move #1 cylinder to TDC on the compression stroke, tighten down rockers on cylinder #1 to where the pushrod feels slight resistance from the rocker arm & lifter. Tighten down about 105 degrees (12 o'clock to 4 o'clock)
14. repeat for each cylinder in the firing order 184.108.40.206.220.127.116.11
15. install new intake gaskets, seal around the water ports with silicone, install intake manifold.
16. move motor to TDC on #1 compression stroke, install & set distributor to #1 cylinder.
17. install fuel injection, cables, hoses. fill radiator with coolant.
18. Install exhaust gaskets & manifolds, install spark plugs & wires.
19. Put some oil across rocker arms, reinstall valve covers.
20. Reinstall accessory brackets, reconnect battery.
20. Start motor & set timing. top off coolant as needed. the motor will smoke as the gaskets seal & the residual oil on the exhaust manifolds burn off.
Your heads are probably warped from overheating. have them checked out by a machine shop. Sometimes they can machine them back to flat, but you might have to replace them.
Replace the head gaskets.
For sure, replace ALL the gaskets involved. When you purchase, ask for a head gasket set and you will get all the gaskets that are used.
In short you have to take the head off, replace the gasket/s and replace the head. You best bring it to a pro.
if the miles on the engine aren't too high, then just replace the head gaskets. if the whole engine is tired go ahead and swap out the motor. its a lot cheaper to do the gaskets then to buy a new motor.
probably head gaskets are f*cked or a cracked head. either way its not good.
intake gaskets are between the head and intake. head gaskets are between the head and the block..
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.
Remove the head, Grind it flat and replace it using a new gasket.
No reason to if the intake gasket is the only problem you have. If engine was running smooth and was not overheated then there is no reason to fool with the HEAD gaskets
Head gaskets, head gaskets, head gaskets
it would be best because you could tear the old ones while removing them.
what is the preceger for replacing the head gaskets on a 1993 chevy suburban 4x4 350
Head was redrilled
You cannot repair a blown head gasket, you must remove the heads and replace the gasket.
Remove carburator then intake manifold then cylinder heads
replace the cylinder gasket and check for cracks and replace the head gaskets
Head gaskets are supposed to last the life of the engine. There is no "care" specific to head gaskets.
I have a 2002 Olds Silhouette and had to replace the head gasket set 2 years ago. It raun around $1,700.00
are you sure its just a blown head gasket?... if heads are warped due to overheating replacing the gasket wont help you will need new heads as well. You can get a Haynes Manual or Chiltons, they will give you step by step guidance on replacing your gasket.
