My 7M with 120K miles and a blown head gasket had 180psi on every cylinder. You say only one was low but thats 1 too many if you catch my drift.
I'm thinking more manufacturer defect than a bad injector. Let us know what happens. |

Well thing is, i called jasper. The warrenty guy that talked to me said its not a defect. Hes saying its my fault. I dont see how but ok. Not many things cause a cylender to lose compression like that just short of rings breaking in two. I dont know what to do now. They wont warrenty it.

Well i think im just going to do a rebuild and do it right myself. I priced myself around 3k for starters.
1100 rods, Brian Crower (1500hp rated) 715 pistons, Ross Pistons 125 head studs, ARP 180 head gasket, COMETIC 265 engine gaskets, Toyota 65 main bearings, Clevite 30 rod bearings, Clevite 73 rod bolts, ARP total w/o machine work : $2,553 Pricey but could be a promising set up after future fuel and turbo upgrades later.

It's no worse than re-building a stock engine. But I would stay on them.
Obviously something they did is wrong. I'm sorry to hear that, I for 1 will no longer direct anyone in their direction as for engine alternatives. |

There telling me im getting detonation and its probably blowing the inner head gasket. Thats why i have compression loss. Although i dont have any coolant issues.

well i guess im hoping it could be the headgasket in that cylender. That would explain it, although i havent been having coolant issues and my oil looks normal. Yesterday the temp rose up to the top and dropped right away. I dont know what that means.

See, I'm not the only one who thinks you didn't have enough fuel.
Run a block test to see if your HG is blown. I would add ARP main studs to that list if I were you. |

well if it happens to be the hg i dont plan on doing a rebuild. Ill simply get a mls head gasket with some arp bolts or studs. Since theres only 3k miles on this engine and its a mild blow, the head should still look brand new. Although ill send it out to get resurfaced. The block however should be ok. Well see when i pull the head. As to the fuel thing. I dont think it is fuel at all. I tuned this car specifically to run really rich. Reason being when i did end up turning up the boost. My fuel is there to compensate. I never retorqed the hg and i was running 12-14 psi out of a .57 trim ct-26, thats why my hg blew. I just hope it last till the cash is there to do this tear down.
Btw i hate hacks, where can u get one of those block resurfacing tools you were speaking of? The big ass heavy thing you turn on top of the block?

I borrowed it from one of my boys from this site.
They cost like $400 but I don't know where he got it. |
