I measured the block and head, they seemed normal so i didn't do any milling, just sanding (1200 grid) backed with aluminum block.

I didn't really check anything about that gasket but the guy who selling it told me to buy that one. it was 2-3 years ago

even a little bit increase in compression is enough after torquing the head bolts down, spin the crank with hand, make sure you have enough valve clearance

i took 0.5mm of the head

been driving with that for some years allready, just now have that collapsed lifter and didnt want to spend 5 times more money for just the mopar name on gasket...

next time i also wont buy comp cams lifters... 3rd time i seei some thousand driven lifter fail.

was working in workshop for a while and now have some free time again so back to work.

washed inside the intake but seems there is still little bit dirt left. injector seats needs little bit polishing but fine for now.

disassembled throttle body and sunk it in thinner for couple of days and did some buffing inside.

took off the tranny cover to change oil filter so on but there is some water inside

not sure but sounds like timing chain loose and hitting the cover.. take a thin screw driver, start the engine and check around the engine where the knocking is stronger.

or you can test the chain cranking engine it with wrench and check the distributor. if there is a delay, it is the chain.

have to check that too...easier than taking the oilpan away

but i think that the loudest part is between the oilpan and flywheel :S

it does have a tiny rpm drop when idling. it idles on the first line... i think between 400-500rpm but it still runs great... acceleration etc is fine..
