Been put on to you guys. Just joined the forum today. I have a 2001 1.9 jtd punto , the prob is a week ago, when i started her in the morning a mettalic knocking came from the engine which went of after she ticked over for about a minute. The same thing happened afterwork but the noise only lasted for about 30 secs the same thing happens every day know. At first i thought it was the hydraulic tappets but the noise seemed to loud for 1 tappet to have lost its pressure so now i am thinking it may be the oil pump as it has a valve in it which opens a 5psi when first started, so i am thinking it may have stuck partially open so therefor dumping all its pressure back. Anyone had a similar experience or any other theories.
