Thread: Kind of a Drag

Hiya,

I put the engine together in 1990 but I changed crank twice (With new bearings) and cam 3x. New bearings when I first put it together.

No 1 plug does fire. At least out of the block. Spark is blue.

Compression on no 1 is 138
Compression on no 3 is 140.
I checked twice.

I got those heads just a couple years ago Guides and seals should be good Well, they should.
I quit watching the odometer a few years back. With the rear gears the speedo isn't correct anymore.

And there lays the problem. If the other cylinders are 165 as you said in your earlier post, then you have a blown head gasket between #1 & #3 cylinders. Remove the head, change the gasket, button it up and be done. And be sure to re-torqe the heads this time around...
