beatngu Posted April 11, 2017 Share Posted April 11, 2017 Finally brought the 673 back to life today and noticed the valve side of the assembly isn't seeping oil on all but 1 rocker. I was thinking of dunking them in diesel but thought the pros here might have a better approach Quote Link to comment https://www.bigmacktrucks.com/topic/49497-what-to-clean-rocker-assembly-with/ Share on other sites More sharing options...
j hancock Posted April 11, 2017 Share Posted April 11, 2017 Pull the assembly, open the shaft and soak in almost any solvent. Diesel, gasoline, kerosene, paint thinner, brake clean, etc. Quote JimIt doesn't cost anything to pay attention.

Freightrain Posted April 11, 2017 Share Posted April 11, 2017 I was really surprised when I fired up the 237 and the oil from the rocker tips was marginal and hardly any. I was told it would build up over time(rpm) and be fine. I haven't had the covers off, yet since last spring. 5000 miles and no problems. I think it is set up for very minimal oiling at idle.

beatngu Posted April 11, 2017 Author Share Posted April 11, 2017 Okay wanted to make sure I was on target. Are gaskets still made for the intake and exhaust does anybody know? Wouldn't be an issue to cut my own for the intake and water jacket not too sure about the exhaust though appears to be semi metallic Quote Link to comment https://www.bigmacktrucks.com/topic/49497-what-to-clean-rocker-assembly-with/#findComment-367066 Share on other sites More sharing options...
j hancock Posted April 12, 2017 Share Posted April 12, 2017 Gaskets are available for the manifold gaskets. Quote JimIt doesn't cost anything to pay attention.

Freightrain Posted April 12, 2017 Share Posted April 12, 2017 (edited) I bought a head gasket kit from Ebay when I was working on my 237 and it had all the little gaskets you need for intake/exhaust.
