Very low compression - Page 2

???

Bolts have heads on them, while studs do not. You use nuts on the top of studs.

I could have made clearance for the ARP bolts, but I didn't want to do any grinding while the head was on, and I sure wasn't going to pull it back off. So I just reused the stock head bolts.

I believe so... The rail on my N/A looks nearly identical

Well its off now. Do you guys think these scratches will be a problem with the new hg.

That should be resurfaced! Those "minor erosion cuts" are in the worst possible direction--a sure future leak path.

paulmicin · 04-05-2008, 02:04 AM

Damn, i was hoping it wouldnt be that bad. Whats a good place to get it resurfaced for cheap?

Finally put it back together. put a new head gasket and water pump just because. but its putting out even more smoke than before. when i got the head back from the machinist it had ridges the whole way across the surface. was it supposed to be like that? also its shooting out smoke from the pcv and theres a lot of pressure in the valve covers.am i going to have to take it apart again and have the head reresurfaced? did i not torque it right, i put it to 75 ft/lbs.
this sucks ass

The head will not slide down to the head with the studs inserted.
You have to drop it onto the guidpins and then install the washers and then the studs or you'll be pulling the head off and on till you do it the right way.

Whoa, 50psi on #1 and only 70 wet? So have you replaced the rings or not? Is your dipstick getting blown out yet?

Pardon the pun.

I'd lap that block at home. If that's the worst damage you have.
Mine was much much worse.

paulmicin · 04-30-2008, 11:09 PM

I didn't have a problem lining up the head i just put it on and dropped the bolts in the holes.
the block is smooth i dont think thats the problem. i havent changed the rings. the seller told me it was a low mileage engine that he swapped in so i doubt its the rings.i also noticed white stuff on the oil cap but that could just be this grease that the machinist put on the lobes and lifters when i got the head back. i have the pcv rerouted to a catch can and then to the atmosphere and theres white smoke coming out of the pcv lines.how can there be smoke. there wasnt any before. can all this be explained by a badly resurfaced head?
