Lubrication improvement

.
.

.

To get the EnginePlus lifters well lubricated I take the flexion wave in my hand for a case improvement. To get more oil on the right case half I enlarged the oil channel behind the middle cam bearing about 50%.

During the provement of the case I saw rough edges at the centre selvedge. For better air flow inside the case I machined it.

I use the M8 head strud washers and the wrench size 15mm M8 Nuts for the crank case bolting (like Gene Berg in the good old days). I found 1,5 mm diameter reduction on Günters lathe to get a better fitment.

Keep it cool

During the head work I spot this cooling chanel similar to the oem castings. I tryed to use the original baffle plate but it doesn't fit. So I decide to build my own air deflector using a 1mm aluminium sheet. 4 small tig spots will be enough.

heat check

The small amount of cooling fins of my SE heads brings me to a "zylinder head temp o meter".

I decide to buy a 52mm VDO unit with 4 senders, but the SE heads are machined in that way that the spark plug sender cant use on this heads. I found a better place on the backside of the heads, the hot area near the chamber.

van housing vs. oilpump

.

.

After i get my oil pump back fom GWD (welding the drivegear and adding a o-ring seal) I have to check the clearance between the van housing and my oilpump with cover.

Drilling two small holes, closing with metal bondo and scutter it in a smooth shape that the air flow will not disrupt to much. Ready for powdercoating.
