Review on BILLET ALUMINUM ENGINE 114003000 DURAMAX by Jimmy Bhat

Another quality PSA part. Looks great with the rest of her stuff under the hood of my truck. However, typical personal protective equipment does not include the O-ring. I was able to transfer my old oil cap over with no problem, but at the price PSA charges for machined parts, it should include o-rings. They do the same thing with their racing valve fuel pressure relief plug, no o-ring, but at least they sell that o-ring. I did not see it listed separately.
