the payen bottom end set i used on a mates car had the cork timing gasket.

Briggsy, i had no clearence issues with the piper vernier and piper cam. Any motor factors can get you a cork gasket from a n/a 5.
Ideal ill see what i can sort out today. The cover is only a mil or so off now as ive fitted a thinner washer.
Got some new low cap head bolts for the vernier pulley from my local fasteners today, they take a slightly bigger allen key but identical bar that. The lad that works there said the original one was cheap european s***e
Checked the head lastnight & it needs 3 valves lapping in as there not sealing. Tonight's job..
Also whats the best way to remove stubborn carbon deposits off the valve heads. Ive got the rest of the head cleaned up nicely with some petrol bit the carbon seems hard to shift.
but late here...
Cork gasket from Renault.
isn't 113deg 1 deg retarded? or are you timing the exhaust?
I usually clean valves using a wire wheel on a bench grinder, just try and keep away from the seat.
Im no expert on cam timing to be fair Andy, from a quick search on the net i have got it wrong yet again
What should i be aiming for with new chain fitted..111deg or?
Cork gasket is on order should be here today.
Used a wire brush on a drill in the end, worked fine the petrol must have loosened it. I cleaned the seats etc by popping the valves in a bottle of coke, shifted the bits no bother!
Head is complete now, all valves lapped in & springs fitted. Forgot how much of a crap job it is to do, At least its right. On with the build up next, can't wait to get it back up & running
Head back on. Ive binned the valve stem oil seals as a couple were in bits...Hope the valve guides aren't too worn, Valves fit nicely so fingers crossed..
What clearances should i be using for tappets with this cam, Standard .20/.25 ok?
A couple of pics from last Thurs, No updates as ive mostly been spending my life savings watching the england game at wembley over the weekend...
Engine fully assembled & blinged up...
One of my mates polished the alternator Saves me some graft...
looks good mate , your cracking on anyway , when do you plan to drop it back in ??
brigsy i'll have to slap you if you dont at least clean that carb up! tiz abit of an eye sore and sticks out a mile amongst the blingy bits.
also what alternator is that?
Im going to get the dremel on the carb raj, it needs a spruce up like Alt is standard valeo as far as i know, just the one i fitted when doing the conversion.
Hoping to get it dropped back in this week, Full day session tomorrow. Will start by grinding this engine mount off....
Ive got myself a blue hose kit from Unstablecable to fit Thinking i should have went black now though...
If your up for that we have a deal mate
I'll have a think mate. Did you order the boost hoses too?
No bother mate, let me know if your interested. Ive only got the coolant/breather hoses as i have custom boost pipework for my grill mount ic.
Got the crap job out of the way this afternoon, removing the derv engine mount from o/s inner wing. Forgot how much i hate bodywork/grinding. Its turned out pretty good for rattle cans, not concours but functional due to loads of bare metal.
Next job is get the flywheel/box back on, Then get the lump dropped back in.
Good work lad be rolling soon.....
Had a spare couple of hours tonight so popped the box back on & dropped the lot back in. Going to crack on next week & hopefully have it running for bank hol weekend.
looks cracking sat in there......
great work mate , soon be finished on the road this weekend then ??
Greate job this is nice Van. Good luck
New poster! (less than 10 posts)
Looks great mate Fantastic job. Will be burning rubber soon
Getting there now, Only drivers side shaft, rad/coolant hoses, i/c/piperun & ht leads left to fit. Should be running on thurs night if all goes well.
Go on son!
Did you get it running mate ?? u didnt clean that carb tut tut
Got bored trying to polish the carb, ill get a spare one bead blasted
Had fun with coolant spewing out the head, I left the dodgy plate off the underside as i werent 100% happy how the h/g fitted with it. I only realised that the bolts threaded into the water jacket on the head, that were fun refitting them on the car!
Had it running lastnight, Started first go. Got it to idle at 1k its quite rough though. Shoud it idle fairly good with this cam?
Dont know whether its me or not but the exhaust sounds mega loud now. Test drive this morn if all goes well!
idle will be pretty rough with that DD cam, similar to the original Kent RT200@106deg.
Good progess mate
Well have messed about with the dizzy & got it running better at lower rpm's. Had it idling at 800 earlier but the whole van rattles So have settled for 1k.
Ive noticed there's less vacuum on idle now, Making it breath a little more than it used to. The engine seems so much more responsive even at low boost, might get the wideband on it & do some tuning tonight
Shady video if it running/idling here, a lot louder now!

Some pics of it back together, took on my shady point & shoot cam as my dslr is down the lockup.
very good job
the engine is very nice
Took it for a decent run out tonight with the wideband on, Goes very well. Kept the boost at the same level for now 16lb manifold, will pull to 7200 in any gear.
Im having fuelling problems though, carb needs attention. Im gonna have to pull it to bits as no matter how much i adjust the mixture it will only stay rich, low 12s. the mixture screw is working fine though, It will only make it richer now.
Infact the fuelling is rich in all situations now. Before fitting cam the fuelling were bob on though
Idle low 12s
Cruise 10-12
Wot 11.9-12.0.
The Jetting is 1.2 main, 100 a/c, 1.3 2nd stg & i have previously took the idle jet out to .45, 2mm needle jet. Venturi is stock 25mm..
Piped up the breather system better earlier, Modified the asi hoses to suit, much better now. Also fitted my alloy carb top off unstablecable with one port, Fantastic bit of kit for the price!

Standard idle jet will bring the idle mixture back up I bet. maybe you had an air leak with the old engine ?
The fueling will change with the new cam mate. I would have expected (hoped) it would get leaner than before at higher RPM's - that would suggest it's breathing better. Did you compare high RPM afr ? I'd be suprised if it wasn't a bit leaner above 6000rpm than before
It is slightly leaner at top, With std cam it used to be 11.7 all the way now its 12.0 mostly, Needle jet is 2mm as i were emptying the bowl on stock cam in 4th!
Tested it to 7200 in 4th tonight, fuelling were as near as all the way
ill get a stock idle jet in there tomorrow, There's a black patch appearing on the sill above the exhaust already
Std idle jet done the trick, got the afr to a reasonable level at idle 14.5ish. Starts/idles a lot better!
Have set the idle at 900 ish, Got sick of the throttle plate staying open slightly with it higher, giving erattic idle speeds between 1000-1500. Sounds rough on idle but it stays running so will leave it be.
have you done anything to brace the "Christmas tree" turbo oil feed? I'd be worried about it snapping off the union at the bottom.
btw, I don't know what you set your tappets to, but you might want them a bit looser with that cam, 0.3 probably, but maybe even as much as 0.4mm.
who else on the forum has an extra van?
Looks a mess doesn't it Its been like that for years on my gtt, Not ideal but its still hanging in there. Next months job to sort it out my funds are low.
Tappets are set at .20in/.25 exhaust. Ill admit i know sod all about hot cams, So just kept the settings std. Should i do both in/ex the same? .30?
Tim Biggs has an extra van too Kenobi, Marky mark's creation. That & haz's old van give me the inspiration to do the conversion
I love this van. I actually am in love with it.
Aye it goes well now Ashy, pulls all the way round! It is a bit funny to start up like. Still having problems getting the idle mixture right, Going to change the mixture screw as its not doing a lot.
you'll probably have to idle it in the high 13s. I'd do it by ear and ignore the gauge.
