Hello, I purchased a really nice JDM motor (had bad luck with about 3 not headgasket but rod knock) and the shop just took one head bolt out of time and put in ARP head bolts and torged them down to 84/lb

is this a good idea? without replacing? the engine is an actual good condition one as just looking inside the water housings its all still grey as oppsed to brown/orange from water.

write back thakn you for everyones help.

Im gonna have to say that its not a very good idea not to replace it. Shit your already there when you remove the head studs you shouldnt just went with a lil more insurance and replaced it.

Don't be too surprised say If the headgasket lets go. What you did was disturbed the stock gasket by relieving tension, and now tightening it even more. The wise decision was to replace everything while your in there. I contemplated doing the same with my JDM engine but I didnt, if it's going to blow its going to blow, then fix it properly after.

Quite possibly, the reason why your last engines died might have been due to a leaky hg which allowed coolant to enter the block and cause "rod knock". Just my guess, it's happened to me.

If the HG is still relatively new, it should be fine with a retorque... but if it's crossed the ocean and who knows how many miles are on it; I'd change the hg for a new one.

And since you did the bolts and the head will be coming off....you should make sure that it's resurfaced so you can use a metal headgasket.
