Re: engine problems

Hi enjoy the site.

I've moved your question into the 156 lounge.

Re: engine problems

Ive just rebuilt my engine due to oil pump failure which caused No 4 piston to explode into a million bits. Problem is oil pressure lights tend not to come on until seconds before the engine is about to go bang. whats the problem?

Re: engine problems

The main problem from what I gather is that the engines can use a bit of oil, and people these days are not used to opening the bonnet and checking the level often enough.

The first thing they notice is that the low pressure light is on, and as said above the damage is already done.

Sometimes the damage will only show itself after a few thousand miles when suddenly the engine goes bang.

Been there and got the T shirt. I bought a very healthy sounding 145 QV, 300 miles after the big ends started knocking. The previous owner must have run it low on oil, topped it up then sold it quickly.

James, oil pump issues are pretty rare from what I gather, you must have been unlucky.

You will never be cool driving a Vauxhall.

Re: engine problems

Tropicana - its a bit of a vague question....

As has been said above - running the engines low on oil can certainly cause problems...;
not changing the cambelt at 36000 mile intervals can cause problems..if the belt breaks / strips teeth, you WILL bend valves.

And afterwards unless you change the big-end bearings you have a good chance of running the bearings and risking a con-rod failure...

Unless of course its a V6 - they are much tougher!
