@Pete. I hope the young lady in question values your 'Top Dad' status highly

Oh she does she's a very thoughtful girl and I'm very proud of her.

M_c (won't let me tag) tends to be right on these matters.

To 'tag' you need to prefix the Member's name with @

I rarely get to deal with petrol engines, but have still seen a few with loss of compression on a single cylinder.

If I get a fault like that, first thing would be to look at plugs and coils. Swap them around, and see if the problem moves.
Next would be a compression check, as it's the easiest next step. Plus it rules in/out a base engine fault.
And then having seen those compression readings, it would be the bore scope down the plug hole, and see what can be seen with the side view camera.

Then I can go back to the customer with a definitive diagnosis.

Well, thanks for pushing me in that direction. I was lucky that WM lives so close and had a tester to hand so I could get on with it. Now I should have her car back up and running next weekend

Any idea what caused the valve to burn out in the first place?

Tappet closed up? Or just a manufacturing defect?

Would have thought it was noticeable for a while though, not a sudden fault

For some reason the @ won't drop down names list

It should once you start typing the name. Did it work before?

Used to yes.


It's working again

What tensions the timing chain ?

Had problems with a Seat, all down to the plastic hydraulic chain tensioner.

Just a thought.

No clue. Tappets are hydraulic but none are stuck.

Nope, literally happened in a moment. Could be the valve head was cracked and finally let go.

Steel/ally spring plunger with hydraulic back-up.

Valve seat is in perfect nick so I've de-coked the whole head, ports, valves, everything. Just need to get the new valve now and get lapping. I'll lap all of the vales into their seats and lap the head flat, clean it up and re-assemble.

 

[mtt.tr]

Blimey, sterling effort.

Gotta get my wife's car back off her before she gets to liking it too much

 

[Barking Mat]

Fair play mate, that's getting on with work.

 

[Dcal]

I'd half expected you to get the repete-o-meter out, or at least scrape it flat.

Sterling work

 

[Pete.]

Didn't go to work today still rough from this rotten cold. I managed to get a bit done, valves lapped and installed, head also lapped flat ready to re-fit. Need to build up the cam train now.
