Pontiac 400 Motor Top End Refresh
Posted: Sun Apr 19, 2015 12:49 am
Here's what i've been up to the last 2 months. Decided to bite the bullet and do the top end as it was burning a lot of oil through the valve stems.
Pretty obvious once i got the heads off what had been going on.
Many thanks to Autopontiac for the machining of the valve guide bosses to accept a positive lock valve stem seal!
I'll let the photographs do the talking.
