Travis said:Yes, the idea is based on sound engineering and they are a relatively common item with hot rods and racers...
The biggest question is if their design will cause any leaks. I exchanged e-mails with him a couple days ago and I could see it going either way. He did claim to have owned an Opel up until recently and had to sell it to make room for his business. This design hasn't been tested on a running Opel motor BTW.
So, who's going to be the guinnea pig?
RallyBob said:I'll vouch for the merit of a crank scraper, they do work as advertised. I cannot take advantage of this commercially available one, as I tend to profile my crankshafts and often run aftermarket rods, so mine need to be hand-made (I weld them to the inside of the oil pan).
I see that one is offered for the 1.5/1.7/1.9/2.0 engines, and I believe another for the OEM 2.4's. Has one been designed for a 2.2 litre CIH engine?
Short of sending a completed engine to you, making a modified scraper fit an oddball shortblock is difficult. I normally make the scraper part of the oil pan, and in fact usually make two of them, one low down to remove the majority of the oil, and another tighter-fitting scraper higher up the side of the pan to remove the residual oil. As you said, there would have to be modifications for aftermarket rods, and profiled counterweights, but also for increases in stroke caused by offset-grinding. Just as easy for the engine builder to do the scraper fitting while the oil pan is being fabricated.Kevin Johnson said:Hi Bob,
We do custom mods for the scrapers at no extra charge (like for knife-edged cranks and rods etc.).
If there are some Florida members that have an engine out I would be happy to do a pattern for whatever engine and they would receive a free one.
Is the 2.2 CIH engine found in any domestic cars?
Actually the cam bearings are fine, the cam lobes however tend to wear badly on Opel cams, especially at higher rpms and springs pressures. Never had a problem with the 'left-turn only' syndrome, even after running 4 cars at three circle tracks over about 8 years. Still, I'm interested in how your system works on the track, you can always make improvements over the factory oiling system for sure. Let us know!jeff denton said:(This tube and the puddle it causes is how Mr. Legere oils the rear cam bearing, this can't work in the g-forces we endure in a constant HARD LEFT turn, and actually cause worse problems in oil control upstairs.)
