Hello everyone

i snapped one of the valve cover bolts and I’m struggling to find the part number to purchase a replacement. Anyone who can chime in is greatly appreciated.

I need to drill out the broken bolt … not looking forward to this at all.

Try welding a washer and a nut to the snapped bolt and using that to remove it first before you drill into the head.

 

SNG Barratts has a parts break down - here is the link https://www.sngbarratt.com/English/#...r=1&layoutId=G

 

There are 3 different bolts that hold the cam cover to the head.(which bolt?)

 

Hi, it's similar to this one.

 

This was very helpful, thank you so much for the link.

 

Unfortunately, the bolt snapped flush with the head, I don't think welding here is an option. I love the tip though.

A little late to this thread, but a word of caution on the valve cover bolts - the rear inner bolt is different to the other bolts and studs. It has no location nose to prevent interference with the cam sensor. Fitting a nosed standard bolt on that rear inner position may cause misfires.

See the page on Terry's Jag parts here: https://www.terrysjag.com/category/X...ket-40-V8.html

The standard bolts are #AJ810511
The standard studs are #AJ810512
The rear inner studs are #AJ810721 and requires the mounting #AJ810510

 

lots on e bay

 

...or impale the cam sensor if you're really unlucky

 

I'm not sure that it could get that bad, but it could be hell trying to diagnose a misfire after a cam cover gasket change

I'm just finishing up a chain and tensioner update on my 01 4.0l coupe and still have my covers off. All of the bolts positions are through holes with the exception of the 2 centre bolts and the rear inner which are blind holes. The rear inner bolt hole is 5mm shallower than the centre bolts.

Trying to pull a standard nosed bolt down in that rear inner position will probably result in......snap !
