Hi All,
I had a friend call round today who is rebuilding a Range Rover 3.9 engine.
He bought a set of 16 new tappets from eBay, from a seller claiming they were OE parts manufactured by Delphi. They came in a plain white cardboard box, and there are no identification markings at all on the box or tappets. I always believed that the OE tappets were manufactured in the USA, right through the life of the Rover V8.
Now, when I have bought OE manufactured tappets in the past, they have come individually packed in bags to keep debris out. These were just relying on the box.
He took two tappets out the box and placed them cam face end down on my worktop. He then pressed the push-rod end of one tappet into the body against the spring with a biro. It went in about 8mm. He then pressed the other one in, and it went solid after about 4mm. Several in the box are like this.
He was asking me if I think these are OK to use in his 'new' engine.
My first reaction is NO, but I must confess I have never done this particular 'test' myself, and would be interested what others on here think.....
