VW Heritage T5 Buying Guide

[Transporter]

Might be the wrong time to make an admission here but my trusty old 2005 T5 humble 2.0 litre manual petrol has at times not had the correct oil for that matter many times if the oil needed topping up I would grab whatever I had laying around just to avoid the dreaded rattle on start up [it's my warning that the oil is low anyway ]Whilst I only add a litre or two I can now say that after 300000 kays no issues with camshaft . I wonder why the diesels with lower kays have this issue anyone got a idea I am interested .

Simply because the correct engine oil is more critical for the diesel engine than for the petrol one. There are much higher pressures in the TDIs.

I only have limited knowledge of the diesels but I thought the compression thing was the biggest difference cant see why it would make a difference to the cam .

In addition to opening and closing the valves, in PD diesels the camshaft lobes are used for actuating the PD injectors, which operate on a very high pressure. This is not valid in petrol engines or CR diesels.

Ok makes sense , like I said not a mechanic but needed to know .
