xtcvampire Posted May 4, 2010 Share Posted May 4, 2010 Hello. I found a few bits from an Opel Calibra. Can anyone please tell me if the oil cooler assembly from a c20xe engine would fit to a CIH 20E engine? I'm interested if the sandwich plate would fit. Is the fuel filter thread the same? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
mantaray Posted May 4, 2010 Share Posted May 4, 2010 Yes I think they both use the same thread for the oil filter. So you should be able to use the sandwich plate. Quote Link to comment Share on other sites More sharing options...
andyc Posted May 5, 2010 Share Posted May 5, 2010 No, sorry Chris the oil filter thread is different. The C20XE takes a metric oil filter(GM No 93156954) and a CIH takes an imperial filter (GM No 93156958). Now the metric filter will go on the CIH thread but under pressure the filter will blow off and deposite the contents of the sump all over the road. The sandwich plate will fit but you need a filter thread from something like a 3.0 12v Senator or Monza Cheers Andy Quote Link to comment Share on other sites More sharing options...

mantadoc Posted May 5, 2010 Share Posted May 5, 2010 Just as an aside, look for sandwich plates that include an oil stat. Over-cooling oil can be worse than it being too hot. Lots of cars don't have one because they really don't need it, and if it only needs it for 10% of your driving but you over cool the oil for the other 90% you're better off without. Imperial thread on a German car, life is strange. Random thought: What is the thread on the end that goes in the cars oil pump casting? If that is the same on both, and it might be as they have the "hex" to fit them in "the middle", it might be a case of using the metric filter to match. (then adding that info to your cars documentation / an alloy plate somewhere obvious to avoid issues later) Quote Link to comment Share on other sites More sharing options...
xtcvampire Posted May 13, 2010 Author Share Posted May 13, 2010 hello. I'm still looking for an oil cooling sistem. Excepting an Opel Senator/Monza from what car could I use a sandwich plate that would fit my 20E CIH engine? Quote Link to comment Share on other sites More sharing options...
andyc Posted May 13, 2010 Share Posted May 13, 2010 any 12v straight six except a 24v as these are built into the timing cover Andy Quote Link to comment Share on other sites More sharing options...
