Hi all,

My 1997 SL500 has been ticking for the past few thousand miles, evidence of the plastic Cam Oiler tubes possibly having failed and 'popped' their ends off.

I was experiencing the usual symptoms....ticking engine, oil pressure at 3 bar when under acceleration, but often down to 1 or even 0 when hot and stationary.

I managed to find some used and degreased metal tubes on the 500E forum and for a little over £100, received them in the post from the USA.

A good friend did the work for me, replacing the rubber O rings on the tubes and fitting new gaskets. It turns out that just one tube had popped it's end and now, the car is almost silent without a single tick.

I'm very happy to say the least.

Here's to many tick free miles :thumb:
