VW Polo 1.9D '96 Tappets (cam followers) - cdc281275
Hello,
tappets (cam followers) are knocking on my 96 Polo D CL (108k). A mechanic said it sounded like maybe 2 had gone. I have no oil leaks, no oil pressure warning light. But my wife says the power (what little there is) has dropped off a bit. The car's been serviced every 10K since 65k (when I bought it)

The above mentioned mech. said the oil pump may need replacing (£60+) as well as the tappets, but would need to do an oil pressure test to determine other underlying problems in case the oil pump is OK. He said £80 plus vat for the test alone!!! Is this about right?? Is he trying to rip me off?

Do the tappets just give way, or is there another reason for them going?
How long will the engine last with, say, 2 or 3 tappets shot?

thanks in advance
