Hello all,
I'm proud to say that I've now joined the ranks of Z owners, having picked up a 260Z a few days ago for a project car.
In the process of trying to decide whether I should attempt to get the car running with the L26 in it, I decided to do a compression check, and got some strange results that I'm hoping you can help me interpret.
As measured from the radiator, they're as follows:
132 - 120 - 150 - 136 - 135 - 124 - radiator>
Now, they seem fairlyl in the zone, save the freakishly high compression in cylender 4. Now, I don't know whether that means that cylender four is healthy while the rest are crapping out, or if there's something wrong with No. 4.
The other strange indicator is that the engine doesn't turn over smoothly - it seems to "stall" every time cylender 3 is compressed. It makes a sound like...whiirr cachunk whiiiiiir cachunk (pardon my terrible iforum onomonopia).
In addition to that, I'm not sure how exactly to do a compression check - do I crank the motor several times over (which usually gives me increased compression with every turn, then it tapers off) or just once?
Thanks for any help you may be able to provide.
