Where did you get your information from to get that percentage? Have you had a personal experience? And ill be updating tomorrow after noon when I get the head off.

 

I had a blown head gasket in my 98



I replaced everything before doing a compression test finding they all were at 150 but 3&4 were at 50. I would suggest a compression test even after going to the garge. The low oil psi I heard was a jeep thing. Even after I replaced the gasket and head I had low oil psi. I replaced the oil psi switch and it worked for awhile but now my oil psi drops most of the time when I'm not giving it gas. Put I haven't lost any power at all

 

Opps didnt see the pressure test.lol.If you end up replacing the head just look for a 0630 off eBay I got mine for 200 with springs and valves shipped to my door. Good luck

 

Could be. TUPY is located in Michigan

But they have foundries located in other countries.

 

Yeah ive been shoping I like what Clearwater heads have.. 425 plus 30 shipped anywhere in the us. 5 year unlimited mile warranty. No up front core charge. For a complete new head I know what ill be saving up for

 

Head off now to operation head clean up to find crack... any ideas of what to clean it off with and where?

 

Clean everywhere the headgasket sits. If that's a cast iron block (and not aluminum) you should be fine with a wire wheel on an angle grinder although i DO NOT recommend that approach.

I personally use a Scotch-brite pad. They even make them in discs that you can put on an angle grinder unless you like using your elbow grease. I spray brakekleen onto the block and then use the pad to clean it up and repeat.

 

alright i have a bunch of of that scotch bright stuff...it is a cast iron block and the head as well. so on the head i didnt take a picture of it but it is super dirty its safe to clean it with brake cleaner? and i dont want to run the stuff down the sewer at all, soo any bright ideas with little to no clean up?
