I got it with the engine bout 2years ago for a guy in scotland. i was told it was rebuilt 6th months befor and it look pritty clean, and when i took it appart all the bearings an seals where good. just thought it was bout time it had a service.
I was thinking it was a diy job.
That was the very reason i rebuilt it, excess porting. The side of the oil way blew out and filled every thing with oil!!!
Im an engineer so i sleved and welded the oil line and then just cleaned and smothed it out at work.
im putting the charger back on at the weekend and hope all is good!
