i recently been having issues with my triumph these last few weeks. i decided to take the heads off and noticed oil being left on the cylinder walls.
Took the cylinder off any found some interesting things
Looks as if i need to tear the motor apart and replace the lifters and cams
Whats your thoughts?
The pistons are scored by the rings but overall they seam reusable, only issue is the wrist pin is stubborn to get through the piston but the wrist pin bushings look great and are in spec
The engine has suffered from dirt, but in dirty engines with no other faults the bearings exhibit pronounced wear in a band in the centre of the bearing where the oil hole is. This is where the dirt first comes out into the bearing and causes the damage, your bearing wear is across the full width of the bearing which suggests there are other issues such as low oil pressure caused by incorrect clearances and/or oil issues as well as dirt.
