she runs!
 
runs and drive on throttle bodies on speed density,
only prob i now have is the top end is very very rattly, but it has been stood for a week and a bit.
anyone know how to stop the tappets from rattling like hell, never used to do it.

add a turbo to the hotside, that might cure it ;)


post pics! Sorry im no help. :bang:

Congratulations! I honestly didn't think you could get idle working on speed density. No offense intended and you proved me wrong, anyway.

How do you like it? Power, drivability sound?

Not sure about the lifters but if they're hydraulic then check the oil pressure. There may be a small chance that it's the problem but...

sweet how does she move?

stevenford_uk 04-02-2007 03:53 PM

the noise is awesome, absolutly mind blowing! and very very very loud, completly drowns out my very loud exhaust! :gtfo:
there is very good oil pressure as my idiot gauge is up the top end of things.
i have not touched the tuning on the ms from my std setup so drivability is as good as can be expected, she lurches a bit, runs rich at low rpm and lean up top end and mid range.
but i clogged it in 1st and it spat me bk in my seat like its never done b4 and there is a glorious soundtrack to boot! so i am very happy with it in general.

but those lifters are soooooo annoying:vash:
i am going to wait until tomoz night after work then strike her in again to see if its any better after the oil has been around them and drained away. if its not its time to whip my cams out again and compress each lifter manually and put them back in completly empty to see if that solves it (i forgot to do that when i threw it all back together the other day.

Well done, mate. I'l bet it sounds amazing.

As for the tappets, I've found cleaning the oil system the engine with flushing oil has helped, although going over to a Mk2 head really fixed it!!

Congrats! Did you get your kit from Bill?

yeah kit was bought from bill and he was great, his after service is fantastic.

as for the tappets i ripped out the cams again earlier and none of the tappets had any oil in them, there is oil getting up to the top of the head but none into the tappets, so i banged it all back together after oiling the hell outta everything and ran it up for 10-15 mins, was getting very high oil pressure at first on idle (5 bar!) but after a visit to 7500rpm it dropped down to normal levels at idle. but was still noisy so i think a drive may help it a bit with that.
just gotta get the tps hooked up on hybrid alpha n and get my new wideband lambda in
