I doubt it makes any difference i just drop them in no way they always land right way up lol

Important thing in my experience is to tighten it up properly and retighten after its run and cooled as the copper will soften with the heat so needs a bit more tightening

I noticed that they felt almost loose once retorqued they were fine

I'm finding I'm leaking more oil now they before so need to strip to see. Don't think it's leaking from the copper seal but I wasn't sure

The copper injector seals are into the combustion chamber so if these are leaking oil you've got MAJOR engine issues ;)

From what I gather, the rocker cover/head has separate seals around the injector body which is where oil around the head usually comes from - happy to be corrected on that though.

That's correct I put a dab of oil on mine this time but it's such a tight fit so easy to damage them

This is what I found when I took the injector out. Either it was stuck or the reason the last owner put 2 washers is eveident any idea what this would be the bolts were tight

The little bit of carbon left I cleaned up but I'm sure the seal went all the way to the injector

Car run fine like that lol only was leaking oil

The injector seat tool cutter I had seemed to be rubbish swapped it over and it cleaned it up good

That's probably what all that swarf is

Any tips I drifted the top seal in neatly and flush used a tiny oil to stop the seal snagging on the injector as I push it in as it's a tight fit alternated tightening the bolts up

It leaked less before with a knackered top seal lol

I have redone this oil seal as it was torn when I took the injector out

I seemed to be able to drift the seal in more this time (I think)

Once drifted in though the middle of the seal looked like it was going out of shape

Like the holes too small and it's squashing it

I was very careful pushing the injector in flush and straight and watched the seal and it looked ok as I was putting it in

Is it worth using a dab of grease to slide it in better

Both the last 2 seals seem to have torn on fitting

Looking at the manual looks like I've been fitting then wrong I normally leave the lip of the seal over the hole

I can't see how it will stop the oil this way

How does It work
