if you cant get thoes bolts out it might be worth a bit of research before you go looking for new block.

ya cuz there are some people in cali who have put in a BP but i couldnt get any definite answers..the guy in my town who smogs cars says i have to take it to a referee station to see if itl pass. but i dont wana spend 2k and not be able to use my car lol

ok got everything out except the block, the freakin bolts on the strengthening piece attached to the block were stripped lol had to cut em with a dremil cutter...here are some pics of the pistons and everything else.

as u can see the pistons have a ton of oil on them and look really burnt, and with the headgasket heres the weird thing. about 4 of the coolant passageways were blocked? weird huh, i dunno weird stuff

the pistons dont seem to worn, just baked on oil. in my opinion (may not mean anythign) those parts seem pretty good. if i were you i would buy new oversized piston rings, new valve seals, and get your block milled out (if you can ever remove it from your car) so teh new piston rings will fit.

if anything take some degreaser to the pistons.. just make sure htey are complaetly clean befor eyou put them back in the engine.

of course if you had 1500 laying around or so, and cant do an engine swap, get new pistons, connecting rods, and even a crankshaft. that should keep your engine in shape and good compression for another 150,000 miles. plus you can reclaim alot of the stock power.

hey thnx guys for the support, sent the head in today should get it back in bout a week...ya ima clean everything then put it back in, umm quesiton. should i get the blocked check as well? cuz its gonna be a b---- gettin it out, just wana know just to be safe.

WingleBeast · Post by **WingleBeast** » May 17th, 2006, 11:24 pm

well if you replace the rings... (which you should to save your compression) you need to mill the head out. so....

Bumpysbro · Post by **Bumpysbro** » May 18th, 2006, 1:26 am

ya, the thing i dont get is why my compression was soo bad? but everything seems to be in ok condition? like i was gettin 120, 80, 90. 110 and my rings seemed to be in good condition? hmm weird

WingleBeast · Post by **WingleBeast** » May 18th, 2006, 4:05 pm

maybe some of your spark plugs wernt doing well

Bumpysbro · Post by **Bumpysbro** » May 19th, 2006, 1:38 am

ya all the spark plugs were drenched in oil when i took em out, had to be cuz of my valve cover gasket wasnt sealing properly i guess. it has silverish shiny color, like oil and coolant mixed.

Bumpysbro · Post by **Bumpysbro** » May 19th, 2006, 2:36 pm

this is really weird, ive been cleanin part after part lately...cleaned the intake manifold and prob a liter of oil was washed out, and same iwth the pistons, exhaust mani and strengthening block. very weird

the spark plugs don't have anything to do with your low compression. they aren't even in the motor when the compression test is done. the guage is hooked up to the combustion chamber through the spark plug hole.

if your compression is low, there are 2 things that could be wrong. either your rings are bad, or your valves aren't sealing properly. you should wait until the tech reworks your head, then ask him how the valves looked. of course even if your valves were found to be bad it doesn't mean that your rings are still good.

if i were you, i would buy a set of stock size rings and the main/rod bearings. then all you have to do is hone the cylinders and put your engine back together. since you already have the engine tore apart it isn't that much more of a hassle to do either.
