Re: Can't push wishbone pin into bushing. Any tips?

All done. In the end I used a bit of washing up liquid and some water.

Can't push wishbone pin into bushing. Any tips?

I am fitting new wishbones to the polo (aluminium subframe) and I just cannot get the pin to go inside the bushing. I have marked a line on the edge of the hexagonal pin so I can see it is aligned correctly, but it just won't go. I have tried levering it in with a small crow bar, but not moving a ...

Periodic epc light, but no fault code?

I replaced the head on the Polo on Sunday and now it's running great. Compression is where it should be across all cylinders and the spark plugs are a nice colour too indicating it's running well. Before I started the head my daughter did say the EPC would come on but make no difference to the ...

Re: Will a clogged cat converter cause carbon build up?

5 months ago it was the exhaust valve on cylinder 3 that went. This was deduced by an initial compression test and then a leak down test. Having removed the head I poured water in the upturned head and the water flowed out through the exhaust port. This time around it was the same problem on ...

Re: Will a clogged cat converter cause carbon build up?

Before the engine management light came on and the valve failure the only light that did keep coming on, but I stupidly ignored was the EPC light.

No error code to hand though as when I hooked it up it was just reporting the P0301 misfire code.

Will a clogged cat converter cause carbon build up?

Just trying to work out why the head I put on the polo only lasted 5 months before I had the dread low compression due to an exhaust valve. The valve wasn't burnt just was sealing and as a result really low compression.

Just trying to work out what I should also replace as I really don't want to be ...

Do I need to replace timing chain and sprocket after 5 months

I am having to replace the head on the VAG BMD engine code in the polo after just 5 months. Last time I did this I also replaced the sprockets, chain and followers. Trying to keep cost down and was hoping I could avoid the extra expense and not have to replace all of this again. Car has done about ...

Re: Another burnt valve. Only 5 months since last one.

I have found a company in Cornwall who do a whole exchange head for £225 + vat. Given the trouble I have had with the head on this one I think I am just going to go down that route.

Re: Another burnt valve. Only 5 months since last one.

SO having removed the head I turned it upside down and filled each of the cylinder tops with water. Low and behold water quickly started draining from number 1 and out of the exhaust port. In fact I put my bright led light into the exhaust port hole and you could clearly see the ring of light around ...

Very low compression within a couple of weeks?

Replaced the valves on my daughter's polo 5 months ago because of low compression and the car was then fine. 2 weeks ago my daughter reported that whilst driving along the car lost power, but then it came back (no engine light on) the other morning she reported that it took a long time to start and ...

Another burnt valve. Only 5 months since last one.

Beginning of May I stripped down my Daughter's 3 cylinder BMD engine and had new valve seats and the head skimmed as a result of poor compression. This solved the problem and the car ran fine. Cut a long story short the engine management light came on yesterday and it went into limp mode. Got the ...

Re: Bent valves after refitting head. Can't think how?

Maybe. If anything I'd have expected cylinder 1 to be bent as when at TDC 2 and 3 are well down in the block if it had happened when fitted.

Bent valves after refitting head. Can't think how?

I had the head refaced and new valve stem seals. Refitted using the timing tools, but as soon as I started the car it was running roughly. Stripped head off and asked the head refurb company to look and they said one exhaust and one inlet valve were bent.

I am sure I checked the timing after it ...

Re: Replaced cylinder head, but now runs rough and wont even idle :-(

I have dropped the head back to the company who were very forthcoming to help rectify the problem. Having taken the head off I was going to test the cylinder block for flatness, but wanted to ask whether it is possible for this to be out as I don't have an accurate straight edge. Haynes state a ...
