so it's the red bit I'm guna look at making...
I've got a spare you can have mate
I'll see if I can get in contact with my fabricator that's on the missing list as I gave him three covers last year.
Sprocket is a bit ruff...but all sized on dia...just to give you some idea of room from face on veiw..

here's some pictures of a timing cover i made a few years ago for my old c1j, i tried to sell them for a £100 on the club and no one was interested
It's down to how much is the hassle worth to me really... Iv never had to re-take one off to adjust the timing I can just imagine its a pain in the arse and I don't like pain in the arses.. I'm guessing its a case of people had to pay people to refit these to their running engines so they didn't see a point.. But now people are keeping there 5s for longer now. Eg me if its going to save time in the future I'm in.
well when i timed my cam in i think it was around the 114 mark(but it could of been wrong), and when driving it was fairly useless turbo came on around 4500 then you could feel the cam come in around 5500 which felt like the turbo coming in twice it was strange but i didnt like the delivery. i thought maybe id got the timing wrong so thought id advance it, then doing it in a rush after work and had to drive it home i moved the timing the wrong way lol. so that was 1st attempt. second time i had to take it back quite a few degrees around 12 i think i tried (to take the initial adjustment out which was about 5 degrees, i was trying to see what fully advanced was like compared to the fully retarded id experienced) when id adjusted it the wrong way the car was idling quite lumpy and would barely produce any boost(which i think some members have blamed the turbo on before) thats pretty much where it sits now so i think its quite advanced and would like to retard it a couple of degrees, i think this showed in my power graph by loosing power higher up the rpm, but i was still impressed by the power/torque it made. Its either change my cam timing to suit my turbo or maybe a smaller exhaust housing to suit my engine/timing.
Either way having an adjustable cover would of made it soooooooooo much easier, taking the cover off ruins the cork gasket and theres allways the chance of it leaking after you put it back together.
There was also someone else who made their own a few yrs ago and IIRC it had a viewing window. Quality was awesome. I forget who it was.
next batch rockers done..
Oh dear, I think I've had a trouser mess.
These are the STD Ratio Rockers aren't they Sid? They look like a quality piece of kit!
First timing cover done..
Nice job Sid keep it up
Get deposits first this time!
made some of these up other day for David Clark.... will be making more soon if intrested send us a message..
How much for the longer tappet adjusters? Could do with some for mine.
yeah me too.... i had to file my rockers flat so i could put the nut underneath as my reprofiled cam had obviously had a fair bit taken off lol.
Mine are underneath too, but I didn't file down the rocker arm
sweet
I know mate when your fiddling with it. Scared if dropping the nut hahaha.
The longer adjusters are just £20 deliverd..
looking at doing these...10mm copper feeds for inlet manifold water...to turbo ect..
stop them restrictions..

why not see how much you could do the following for? (not for me personally, just a few ideas)
cam followers.
adjustable cam vernier.
oil pump cores?
Cam follows would be good but there are a few processes to making them, like the case hardening for good wear resistance.
I'd like to see a set with a DLC (diamond like carbon) coating as this has excellent wear resistance and super low friction! Still a relatively new process but achieving great things in many different applications.
Not sure how a standard spec set or a DLC set would compare to an OE set for price? Isn't still 200 sheets for a set from Renault?
Cam follower....depends on steel and how silly hard you want to go...not be anything near the £200 mark....prob £100 or less..

yes mate Solidworks is the bomb...
Guna 3d print 1 of these tomoz see how it fits...got an engine just for trying all this stuff out...
All fits in same space just lifts pushrod up 7mm...and with most foke strugling with the nuts.... on adjusters this will be 2 birds with 1 stone...lol

how much are the rockers? and would they be of benefit to a standard engine, turbo, cam setup ?
