x2 The machine shop seriously f'ed up your block!!! And you're going to shave the head and not expect more problems?

Just get a new motor. Or double stack some 2mm headgaskets.

How high is your compression? try a OEM gasket this time?

what pieces did you send to the machine shop when you got your block resurfaced?

1. Block
2. what else?

Get a new block. Had a DE overheat twice, took apart the motor and #4 cylinder was warped. Bad. Once you overheat the SR aluminum block more than once it will never be the same.

I've had my old de get to 240°.... For about 3 months its driving it with a ga radiator, until I had money to but abetter radiator.....never blew steam or a hose....

But a year later it did get rod knock...

I wouldn't think 240°F would be enough to do anything to aluminum. Our aluminum blocks deal with 260°F oil temps all the time. It's the real high temps you get with catastrophic coolant system failure or localized hot spots (air bubbles) that do the real damage.

105 deg on the EMS translated to about 3/4 of the heat gauge range. This is more or less the max that the motor saw on the way home. In general it was around 95 deg.

What's the current CR?

The pistons are 12.5:1

The head has never really been skimmed so the chambers should be close to stock.

The amount taken off the block was compensated by the 1.9mm headgasket I used on the last round so CR should be close to 12.5 still.


To answer the other guy's questions the block and oil pump were sent together when the block was skimmed.
