Helo again everyone,

I'm considering some comments made in my last post.

To reiterate, I'm swapping out the bottom end for a rebuilt one and found the head as seen below. Its not a great pic, but what we're looing at is #5 which had big time blow-by (super low compression, normal during wet test). The remainder of the valves have a thin brown coating which can almost be picked off with a fingernail (see the intake on #6). Other than #5 being a pig, there is no indication that the head should require a complete rebuild.

Its also important to note that this head was rebuilt < 50,000km ago, but obviously has a coating due to the high mileage (1/2 mill kms) and the bum rings in #5. What are my options here? Is there a way to clean this up without doing an entire rebuild. If I bring it somewhere can they tell me if the guides and seals are OK without breaking the bank? Can they/me clean this up safely/economically.




Not trying to be cheap, just trying to be cheap

Thanks again,

Dave M
