T4 RS500 damper to YBP cam cover??? *** Problem now solved, what d'ya think ***
Need some ideas please folks...... How am i gonna make this fit?
should I fabricate a bracket of some sort?
I am painting the cam cover after btw....
Are there any better dampers out there for the job. I'm trying to keep the 500 theme (turbo, damper, inlet 8 injectors etc) so would prefer to use the 500 damper.
Anyone got any pics of this done before?
Any advice appreciated.
Cheers,
Jim

500 theme wit a YBP cover ?? Not very 500 !! lol
But that looks the t*ts !! Think a 500 damper would spoil it !! I like the one Karl does, but thats on a standard cover, Martin would deffo be able to sort ya something tho & look as good as the rest of the engine !!
Really really likin the look of that !!

. Unfortunately means stripping head off to do properly....Obviously you could make a hanger that mounts on the cam cover bolts, but I don't like them as they look too after market in my opinion. I like mine, as it looks factory fit

Fabricated a bracket out of ally, had it welded on and the whole thing sprayed up. Very happy with it. Its an old damper on at the mo, will be getting a new one soon.
Pics dont do it justice, but you get the idea
. what d'ya think?

Just keep an eye out for it cracking mate, its thin soft ally with the brace hangine off it....if it fractures you have oil on your turbo for sure...just keep an eye on it would be my recommendation.
Superb craftsmanship though

That looks awesome but I would say recipe for disaster. Not convinced the cam cover is strong enough to hold that and like said above that last thing you want is it cracking as its got engine fire written all over it.
Top work though. It looks bloody great. I love it when people think different and come up with a new design!

Thanks for the comments all.... i here what your saying and i will keep an eye on it. I think tho (hope lol) that its been made so it covers enough surface area to spread the load. It also covers the bend of the cam cover which i would think would be a bit stronger (hope).
Only time will tell...
Thanks again

Just to save you going to such an "extreme" length of binning it, how about just stripping the finish off and using it in an unfinished state and regularly die-penning it to see if it is going to start cracking.
I know it is a risk, but if it starts getting small stress cracks BEFORE (if) it fails completely, you should be able to pick these up pretty quickly?
At the end of the day it is your engine, and I wouldn't want to suggest anything that may cause a fire
, but it looks so good that I would be trying anything that was acceptibly safe to retain it (perhaps a flat metal shield can be temporarily rigged up or the manifold could be heat-wrapped just to protect it from a worse case scenario). Plus carry a fuck-off big extinguisher in the car just in case?

gutted.No mate, something i should have done but didn't for some reason.
slipped my mind.

my concerns are without knowing exactly what alloy the cam cover is made from it is impossible to specify the correct filler wire, also due to the welding process it will have locally annealed the area, resulting in hard bit-soft bit-hard bit which is very likelly to crack, although i would guess that it would litrally snap the weld and not the cam cover, ideally you need to know exactly what filler wire then have it heat treated after weld.
my suggestion would be to machine two holes that run from the inside of the camcover into the main body of the support and then screw in a couple of counter sunk bolts

Been thinking bout this a lot since reading this thread and i have taken all the concerns about the integrity of the cam cover under load as a serious concern. Then i thought this... the original RS500 T4 damper is a friction damper (am i wrong?)
so.. forces on that part of the bracket should have been diminished by the damping of the RS500 damper.?! (again, am i wrong?)
Anyone remember DESERT STORM? correct me if im wrong, but did that
motor not have a damper welded to the cam cover? (not a ybp i know)
What i really need is the tec boys on here who know about force/ sq. inch to have a look at it and make a calculated dicision.
Any engineers on here care to take a look? all expenses paid. PM me.
Cheers,
Jim.

If you stop the oil from getting on the exhaust in some way in the event of a catastrophic failure (as described above) and monitor it extremely carefully, then that is all you can do, as it is not going to be a crack caused by pressure / weight, but in my opinon - vibration / harmonics from the exhaust transferred into the damper.

I see your point mate, the welder i used is the bollox so not worried bout his welding (30 years at Bentley). your advice bout the bolts is what i said to my engine builder. He said yeah, its a great idea but do i really want screws inside my cam cover that could, potentially come loose? i said no.
Could you not put a spot of weld onto the bolts? Its not like they need to come off again is it.
Just a thought.

End of the day dude, it looks good but can potentially be catastrophic....so weigh it up. In my thoughts it's a no brainer; get rid and start again, maybe following mikes idea of welding a 2wd bracket on the side of the head, or have your welder fab you up a piece of plate, you know the heads strong enough there as the 2wd heads were like that from factory.
Could you live with yourself is one day it ripped a hole in your cam cover and spewed oil over a glowing turbo housing costing you your car? becasue I doubt it'd be easy to put out and damage would almost certainly be massive.
