M35 First Mod and Oil Change...

[M35.Groot]

The intent was to do the oil change and filter including dropping the sump and drilling the 3 x banjo bolts out to 2 mm .

Soooo dropped the sump [ which I might add was pretty clean inside !! With virtually no sludge and the pick up pipe was completely clean ,  explains partially why no turbo failure at 185,000K's ].

Anyhow decide to do the two inner sump banjo's first .

My 2 mm drill was pretty old so went out and bought 3 new 2 mm drills in high speed steel .

The banjo bolts seem to be high tensile but a good drill should be able to handle going from 1 mm out to 2 mm .

Well not so as I broke the drill when it was almost through !!

Not a total disaster but not real flash either .

Went out again and got some cobalt drills , marked out the center and drilled through the back of the banjo bolt and then punched the broken drill out no probs .

Drilled it to 2 mm then just welded up the 2 mm hole .

The other two banjo bolts were drilled out to 2 mm no probs .

As a note used a Z179A oil filter which is bigger than the Z436 and in fact the filter on it was a Z445 which is even smaller than a Z436 .

Go figure .

So oil change done with first mod with only a small hiccup.
