Thread: This could be expensive

at 1.5 cms they are most certainly the rivet for the front seal.... But... Just to play devils advocate 1.5cms is frightingly close to the width of the timing chain so if one had had a very bad loose...


simple test with the sump still off (if it is still off) slowly bar the engine over and look at the chain... that will eliminate your current chain. grab it between 2 pairs of bull nose pliers (put the pliers nose to nose) and try to bend one...

if they were the rivits the metal bends quite easily, the chain pins not so easily.

i pulled the sump off a ford 250 cross flow once and found a stray big end bearing nut rolling around quick count to check they were all there. was probly floating around in there from new .

the scary part is that you know that lol

cheers

I don't know how one can know so much about LR's

Me on the other hand..... Whats a mud sheild?

just that its a plate that sits in front of the front main seal and shields the seal from most of the crud and corruption that gets thrown up at the front.

Not critical in keeping the oil in the engine but critical in keeping the seal in one piece.

oops nearly forgot, as the seal is ment to be installed from the inside of the timing case cover it also serves to assist with the final locating and alignment of the seal.
