Omega General Help / Re: Bargain NON VENTED EBC rear disc and pad set

« on: 06 February 2021, 11:37:18 »

Sod it, got them anyway.

Will cost more than that for a pair of rear discs and if they are YellowStuff pads (description says GreenStuff) will happily send to someone on here for postage

Not a fan of the EBC pads since they put that bedding in coating on.

Might buy for the discs and give the pads to someone on here

Well, it runs and drives again, just got to keep eye on the cam seals as they leaked originally when started but seem to have stopped now.

You left your omega running outside the doctors and it was still there when you came out? What does this tell us? 

That his doctor does not live in Liverpool?

Guessing timing belt as 2007, not timing chain?

Either way, expensive and probably due changing.

Have you got option for a warranty for major components?

I've had the fire ring rust out on an OEM gasket
Also noticed at about 100K+ vauxhall 4 bangers had HG fails
2 thou is not much 
I tended to flat/resurface heads myself in the past on a sheet of thick steel with emery glued to it with no issues .
cleaning up head bolt hole threads and a bit of lube on the threads ensures a more accurate torque
though I always go " click and a bit " 

sounds like you are getting there 

Had to tighten PAS pipe clamps by about 2 turns (bottom of pipe was actually free to move).

Had that a few times on Carlton's ,which is the same reservoir ,so thought it might just need a nip up on yours's   
saves another messy job 

Cylinder head height is now 0.5mm down from original height, any more would be too close to the inlets for my liking. I know you “can” go 2mm as have done that on my old Cav to get rid of corrosion but it had to run super unleaded and “pinked” like hell when cold or on normal fuel

Cylinder head is skimmed 2 thou and my engineer says he has seen loads of these head gaskets failing on different cars recently. All have been redone within the last 5-6years (even from main dealers) and all showing signs of the metal fire rings being the problem so is wondering if the quality of the metal is the problem? Certainly, my gasket was in one piece and not bad condition but you could just see where it was getting past the fire ring.

Omega General Help / Re: Seal kits for brake calipers

« on: 01 February 2021, 15:32:59 »

I must be the only one then that takes the piston out, turns it the other way and puts it back in the caliper and then media blasts the caliper body to get it completely spotless before spray painting and lacquering, then replacing the piston with new, along with a seal kit.

But then, I normally do this on show cars so time becomes almost irrelevant.

Might just need the hose clamp under the reservoir tightening or replacing for the PAS .
sounds like your getting there with the engine 

I can only hope....

I run old Fords and the low pressure pas pipe on those normally goes hard meaning that the pipe no longer seals and the clamp can no longer hold it tight enough.

Am going to clean it all up and see if the pipe is still flexible. If it is, will attempt a tightening, of hard, would need replacing most likely.

Well, that was fun....

Head finally off and confirmed cylinder 3 as intake port all messy compared to other 3 inlets where all nice and clean. Head gasket looks okay but can just see initial signs of gasket going between waterway and chamber on inlet side with lack of carbon (washed away) on cylinder head surface. No visible signs of cracks on cylinder head surface or inside inlet ports on number 3.

All being skimmed Tuesday and everything being cleaned out (breathers, etc) due to mayonnaising throughout intake and breather system. Block to be checked and faced. Will then go back together and see what happens.

Also need to look at PAS bottle and pipe as appears to be slight leak (probably pipe from bottle to pump going hard).

Well, have done a block test in work today and it went green within 3x pumps without the engine even running so definitely coming apart at the weekend.

Just need to do some check before I attack it to confirm ”where” the problem is.

I have this head and the original so will get the best one and go from there.

I believe that Haynes references it

Genuinely surprises me in that, have book on side at home so will check this evening.

Just out of interest, does anyone know the minimum thickness for the X20XEV cylinder head? I know the original is 134mm

Use the cooling pressure tester first. Then bodge up an adapter to use it with your compression tester hose(or weld a fitting to an old spark plug) and use it to pressurise each cylinder in turn. 30 minutes max. At least fixing an I4 is much less work than doing a V6

On the bikes, I have a spark plug with a metal tyre valve brazed in and use a pressure gauge to get up to pressure normally so was thinking of the same this time?

Have a sniffer so will do that first but also planning the leak down as well and have a cooling system pressure tester so can test both ways and also for pressurisation with the engine running.

Is just more work and expense I can do without.
