Oil Cooler pipes. Is there a right and a wrong way to fit them?
This afternoon i got round to start my engine up after fitting new oil cooler and proper Throttle linkage.
After starting the engine up and managing to get it to idle i noticed that each end of the cooler pipes were leaking oil at an alarming rate, oil cooler end and sandwich plate end.
Silly me forgot to put the rubber sealing washers in. Doh!
But what got me was that there was oil leaking from the tops of the cooler. So I'm wondering are the pipes on the wrong way round? Because the sandwich plate has an oilstat built into it and the engine wasn't warm enough, for me to expect oil to start flowing into the cooler. It had barely been running for 2 mins when i noticed oil was leaking everywhere.
The sandwich plate is a Mocal OTSP1. The stat shouldn't open until the oil's around 80 degrees from what I'm assuming.
the oil cooler is always pressurised as the stat is on the inlet connection to the plate, not the outlet - I made a very silly assumption a long time ago that if the engine was cold, ergo : no oil would come out, so I could therefore leave the oil cooler pipes disconnected whilst I backed the car back into the rented garage....
yeah right.. cue 4 litres of oil on neighbours driveway in about 10 seconds
so like most things, I found out the above by trial and error
unless the oil cooler you have is marked for flow direction, the pipes can be connected either way round, btw.
