Cylinder head

[rogerw86]

Hello I have a 2004 LCR 225 I burnt a valve so had them changed along with head gasket, water pump, cam belt, plugs, head bolts etc then it start going though water again! So took it back said he though head gasket looked liked it may have failed so went to put new one on but no fault on gasket but put new one on anyway an got told that if it goes again would mean that the head might be cracked. Now I'm back to stage 1 missing firing on cylinder 3 again sucking the paper into the exhaust if you hold a piece near it so looks like I have burnt a valve again. So my question is I have been offered a cheap LCR 210 an I want to know would I be able to just swap the cylinder head over between that one and my bam225?

Thank you for reading sorry about bad punctuation. And thank you for any advice or help

Hi mate, looking it up on vagcat http://www.vagcat.com/epc/cat/se/LE/2004/268/49/4749059/ Both the AMK and BAM share a part number for the complete head, so i take it they are identical.

As mentioned above, they're identical apart from one has AMK stamped on it

Thank you so I should be a straight forward job to swap over cylinder head between these to engines

 

[mty12345]

yeah as straight fwd as any cylinder head swap is mate.

Tbh, I'd be asking why it's burning out valves. Why wasn't the cylinder head pressure tested if they suspected the cylinder head?

I know I got told because I have a de cat and a badge 5 tip an open cone filter it had messed to much with the mixture. But I find it strange that it would burn a valve out in the same cylinder twice and within 2k miles?

If you remap was done after these mods then the fueling shouldn't be an issue should it?

 

[rogerw86]

Wasn't remapped was trying to get it in for one

that would be bollox of course.
your ecu has closed loop fuel control so will maintain its requested fueling..
unless you have other issues like weak fuel pump, low fuel pressure for example... but that should throw a code for lean running..

BAM/AMK engines are more prone to cracks developing between the exhaust valve seats.. Consequence imho of the factory mapping running them very lean/hot relying on egt protection to save the day (which at 920'c before it starts to fuel dump) is already too late.

So what do you think should be my next step? Any advice?

Find a decent garage who actually know what they are talking about. Some garages are fine for doing brake pads or a service etc, but when it comes to even the most basic thing with an engine they haven't got a clue.

They are obviously a touch retarded as there's no way that those mods can make your car run lean for the reason bill says above. Add to that the fact that they stripped your head, found no problem with the gasket, so just put a new gasket on and put it back together!?!? WTF, like Dan says, why wouldn't you pressure test the head while it was out?? Even more so if they stripped it down twice.

Ffs don't let them do the cylinder head swap for you mate.... you'll end up bleeding to death from your ass.

 

[rogerw86]

No I'm not going back to them again

I know bill been to yours sorting out my tip and ask about remap what you recommend doing?
