2.8 Starts But Sounds Terrible

[daveheggie]

Just got a new secondhand 2.8 ghia with a poor running engine. It wouldnt start so I charged the battery. I now starts but runs noisy and has white smoke coming out of the inlet manifold. there is a burning oil smell how can I check that this is a blown valve. I think thats what the problem is? I am a faily competent home mechanic but have not worked on this engin. any advice would be good!

To be honest you'd be better off on a VW Golf or Bora forum, the V6 engine is the VR6 used in a few VW's and those guys are far more likely to have ripped them apart :P There's also www.vr6oc.com

Of course you could let the resident vr6 nut answer the question ;)

 

The vr6 can be very ratterley after a long time battery disconnection and take time to relearn timming.

 

white smoke

 

There's number of things it can be but ill start with most likley , theres a pipe called a ' vr6 crack pipe ' google that there's loads of pictures of it .The coolent pipe that goes across front of motor which connect's the thermostat on right to the oil cooler then on to coolent pump its about an inch wide and 12 inch long the seal's oftain fail hot coolent lots of smoke etc.

 

The other thing to look for is leaky fuel pipe going to injectors not that likley though.

 

If the rattle continues then the upper cam chain tensioner is likley culprit. the haynes is useless compared to this guide you can change without removing clutch.

I'd start with taking the plugs out and having a look at them which will give you a clue as to whats going on inside, then a compression test to find out if you have leaking valves or broken rings, scored barrels etc.

Thanks for that I willget the plugs out this morning and see what state thay are in. They were new as I had just replaced then when I found the engine dufficult to start. I will look at a compression test but my old compression tester wont go down the recesed spark plug holes so I need to get one that will!
