Default Possible to do AVLS motor headgaskets with engine in car?

I searched, and found no answer. I ask because I know the avls valve covers are a bit larger from my experience doing the gaskets and a valve adjustment.


Has anyone done headgaskets without removing the entire motor? Would I have to remove the cam plates and a bunch of stuff to do this making it more difficult than a normal headgasket in car job?

Should add, without gouging every bit of paint off the unibody so it rusts even faster?

Let me put it this way....I thought of doing this. I popped the hood and imidiately declared "oh god no". That said...with a couple friends and a case of bud, we did my HG's in 5 hrs with the right tools with the motor out.

Yeah. It was an exercise to jack the motor up and move it around to slip the valve covers off......... I just hate to have the car down in this weather since we are going to have some brutal weather supposedly this year. It's my AWD snow car to get my cancer kid to the hospital if needed.

Absolutely - in fact I did one today. As mentioned you jack up the side of the engine you are working on so you can pull the valve cover and get access to the head bolts. I stick a 1.5" to 1.75" tall socket between the cross member and motor mount. I don't remove the P/S pump. I just shim the intake manifold, alternator, and A/C compressor up about 1/2" above the block leaving the two rear bracket bolts in the block but loose.

Bank 2 (driver side) requires removing the cam pulley and rear time cover to clear the heater pipe and dipstick. You have to leave the bottom 3 head bolts in each head and then tilt the heads out (and back in) from the bottom.

Don't know if I would want to try this on the ground - but on a lift it's a real time and labor saver.

I just pull the damn thing so I can replace ALL the gaskets at once. But of course I don't work at a shop or stealership or anything...
