hi im adam

260k? not worth fixing in my opinion.

run it till she blows

haha well i wish i could got plans for it when it blows but i kinda cant afford it to blow right now its my daily driver

hi im adam

it will take a while till it goes... usually.

Depends on how bad the knock is and where its at.

take a pipe/bar and try and find where the noise is coming from. If it is a lifter, it might be worth taking a look at.


Replacing a valve consists of milling a small part of the head so the next valve doesn't stick... and you get a slightly bigger valve.

if you have a mill, its just the price of the valve... but at a machine shop, it will probably be $50-100 for the milling (unless you have a friend) and $20? for a valve.

Thats going the cheap route and not doing the whole head.


A weekend, a tree and a $400 engine (150k ish) isn't a bad route when you look at it on paper in the long run.
