Thread: No compression....

My instructions were very similar. I have the newer studs that bottom out in the block...

all mazworx head studs bottom out in the block.

vacuum test the head, I'm guessing bent valves if it did it with two different head gaskets, especially the factory graphite. You sure you had it in time?

Put some oil in the cylinders...not much. Just enough to see if compression goes back to normal. If it does, then your problem lies in the bottom end. If it doesn't then your problem is in the head.

The head was vacuum tested after the first gasket failed and it was good. I'm gonna do a leak down and I'll try the oil in the cylinders prob tomorrow and report back.

Those instructions are correct. I went through contacting mazworx to verify the torque is correct. Built mine following the instructions and smooth as silk, so it is correct.

Did you tension the head using ONLY the two torque setting supplied by Mazworx

Or

Did you "Torque in factory sequence using the following ratios"

That is, used the factory torque sequence substituting in the 1st and 2nd sequence settings from Mazworx

Well, you definitely have to torque the studs/ nuts in the correct pattern using the FSM as a guide to know the order of which ones to torque first. As for the torque lbs I used what was listed in the mazworx instructions.

I have arp studs in my motor, 60 was not the last torque # in my sequence. Mine were direct from arp with arp instructions. I don't recall what the final # was but iirc, you have to set them in stages. Then loosen them all completely and torque in stages again. I used the assembly lube.

EDIT: I just researched my old build thread only to find I had conflicting info on torque specs as well. Seems I had confusion trying to determine if the specs would change since I had a DET block, DE head, and VVL head gasket. From my postings 5 years ago, looks as if I called ARP directly. Unfortunately I did not post my results, SMH! I've got 30k on my motor, all I can suggest from my experience is to call ARP. From my further forum searching, seems MANY ol Skool "gurus" suggest torquing in stages to 80ft lbs. 20, 40, 60, 80, loosen completely....re-do in stages.

Do you know if the oil pump was bolt to the block when it was decked? This could be an issue with the gasket not sealing. I just skimmed the thread and didn't read anyone bring this up. Could be possible.

Loosening is not required when using the Mazworx studs
