block turbo oil drain on my 1.6?????

[53 willys]

How'd it go?

well I got a couple spots in mind...but I did not tap it yet since I'm wanting to build my exhaust manifold first so I can put the drain in the best spot possible.



hopefully I can post pics next week....long as I get my parts I should be able to.

BTW oil drain would not work going through my girdle....you need to have at least a 1/2" drain pipe for the turbo to drain properly..

Ya I figured you would need to machine a long hole in it not just drill through it.

The Callaway turbo kit that I have uses a Roto-Master turbo. Callaway is VERY specific about where to drill the hole into the block. Go 6" from the tranny side of the engine and then 2 3/4" up from the bottom edge of the block. Drill a 11/16" (hole saw) to tap a 1/2" NPT. then use a 45 degree with a hose barb style to attach the drain hose to. Be aware that when drilling the hole that the angle of the hole is slightly "uphill" so that the oil flowing down the tube has no chance of stopping at the 45 and will drain smoothly into the oil pan.
When tapping the hole, you need just enough threads cut to be flush on the inside of the block (when the adapter is screwed in like you want it) cause the connecting rod is REALLY close. Rotate engine and watch to see there's no contact. Then use the super killer Loctite!
Anyway, thats what Callaway says to do. Hope this helps.

So does your block drain work good?

Original turbos have been known to last 70-80 thousand miles on 1.6 TD engines, so whether or not the drain goes above or below the sump oil level, must mean precious little in practice, right?
At least with the turbos they used.

Then again, the 1.9 TD did feature an updated oil return - to the block rather than the sump, and they've never gone back again...

Now someone please go and remove the oil return connector from the sump of a 1.6 TD VW and see if oil comes out of the sump. Next time you do an oil change, anyone?

well this worries me as it seems that my turbo has been on for the life of the car at 172k miles, so should i be looking in to getting it re furbed etc, but an interesting read non the less, things like this never even crossed my mind,
