rb25det bent valve

[ecl]

hi

just got my car back.. it starts now but i found that :

1) it idles like a wrx with a ticking sound

2) car vibrates with very very rough idle

3) it has 0 compression in the first cylinder

for those that dont know, i accidentally dropped a screw in the cylinder and it squashed it when i tried to start it (doh)

the mechanic said that the problem now is either:

1) bent valve

or

2) piston

he said he's pretty sure its the valve as the piston looks fine

he wouldnt quote me on a price or a range tho

so i was wondering if anyone could gimme a rough price range of getting the valve replaced?

i know the block has to be opened which should cost a bit =(

anyone had similar experiences?

thanx

Remove cylinder head, remove valve, replace valve, replace cylinder head, that's about 8 to 10 hours depending on experience. Say $600 to $800 plus parts, total around $1,000 to $1200 depending on the hourly rate.

cheers sydneykid

also, if i were to replace pistons

would i have to do all 6 at once coz of age differences between new/old piston?

Yes,

you should do them all at once...

If they show no signs of wear (are within factory tolerance), then one new piston with 5 current ones would be OK. Just make sure they balance up the same.

PS; buying a set of forged ACL Race Series pistons wouldn't cost much more than a set of new standard RB25DET Neo pistons from Nissan.
