I’m having a 3.8 built up to go in my xk150. Unfortunately the original 3.4 block is NLA so I’m using a block etc from a MK 10.
My engine builder has asked me to supply a timing chain cover so it can be decked with the block. Rummaging through my bits and pieces I came up with 4 units… All different.
See photo album link here…
I’ve used the stamped numbers as identification. I found an older post of Rob’s that mentioned this was used to match cover to block to bearing caps etc.
Each of the covers has their issues;
OE is from a 120 with a different oil seal size
FSB has severe grooves where the chain must have been loose.
IRZ has a snapped stud
YDJ has a modified oil seal groove… anyone seen this before?
I’m leaning towards using IRZ as long as I can get the snapped stud out of the water pump mount. Any alternative suggestions?
Finally the oil seal:. There are numerous posts about rope versus teflon… Is there anything you suggest I do re the seal before assembly?
