Technical Car will not start, any sujestions?

[J333EVO]

As most of you are aware I've recently had a stage 3 head put on my car as my old head decided to blow a hole in itself between cylinders 1 & 2 when the head gasket went in the same place.

I put everything back together as I found it, but replaced all the vacuum hose with silicone stuff and replaced any old looking hose clips and generally cleaned everything in the engine bay.

I also put on a 40mm TB from tricker, Denso iridium plugs and restuded the head front and back and replaced all bolts on the inlet and exhaust manifolds and new gaskets everywhere etc etc, to say the engine looks good is an understatement compared to the oily mess it was before.

So all's well, or so I thought until I tried to start it! First battery was flat from siting for 6 weeks and of course me running an inspection light from the battery for hours on end didn't help.

So even with a melted plug and no compression in cylinders 1 & 2 my car still started and ran very roughly of course before the old head came off, now with new head on it turns but will not start. There's a spark, theres fuel getting through cos I can smell it off the plugs, but nothing.

Could i have got the timing wrong on replacing the belts as I did spend a long time trying to get it right as I couldn't just line everything up before removing the belts as you would do in a normal change. the head I'm sure came back set as it would be at TDC, and its very easy to set TDC when you have no head on an engine cos you can see the pistons, but any ideas would be welcome.

Timing could be 180° out marks would line up ok but you would be firing on the wrong stroke.

If you've got fuel and sparks, yep I'd go for cam timing. Check the Haynes for all the timing marks - about 10 o'clock on the crank pulley and 9 o'clock on the cam.

Is the bigger crank pulley - one which carries the alternator belt - definitely on right - there's a locating pip to get spot on.

Plug leads deffo right? It's engraved on the coil carriers which leads go where.

 

[J333EVO]

Yes thats what i think it could be, but wasn't sure. How do I check?

take the rocker cover off and you can see the came lobes, so at TDC the lobes at cylinder one should be pointing up i.e. valves closed so which ones should be pointing down?

Aaron.

Ah another good pointer by Pete, I just put the bigger crank pulley back on without seeing if there was any line up marks. Must check after some lunch

Spark plugs are def in right order cos I wrote them down on my handy pad I always keep near whenever I take anything apart. Plus i double checked it against Chubstons car.

 

[HP]

There's a notch on the cam pulley which should line up with a notch in the cylinder head at 9 o'clock, I wouldn't go by lobe positions. Crank pulley (one carrying cam belt) has a mark which needs to be lined up with the end of the ridge on the oil pump housing.

If the bigger pulley isn't on right, the ignition timing could be 120' out.

Is the main connector from the ECU in all the way?

It's alive I tell you, alive!

Absolutely spot on Pete, how I managed to miss something so simple when putting it all back together I'll never know. i didn't even see the little spot to line the alternator belt pulley back up to the cam belt pulley, but it was one turn out so yes the timing was out by 120degrees due to it having 3 bolts, doh! :bang:

It started first turn of the key and sat idling nicely, just need to get some dinner now and take it for a shake down test.

If I ever meet you at any events remind me to buy you a drink, or have a shot of the old girl

Re: It's alive I tell you, alive!

No worries fella, any time. Would be interesting to compare 1242 at 0.3 bar and 1108 at 0.6

York drag strip with Clubcento?

 

[mase]

here is a question about turbo'in a 1242 pete...

do u think van aaken would convert a 1242? or do they only touch 1108, if the latter is tru, how easy it is to take the turbo off and then stick it back onto the 1242 without buggering somethin up?

I just sent my renewal away today for ClubCento so we'll see how it fits in with my calendar as I'm moving in the next 3 months upto Milton Keynes as going to work at an airport near by.

But yeah would be good to compare especially as I have a stage 3 head now and 40mm TB which should liberate a few horses

Oh yeah and the GT brakes which I haven't even tried yet

Any piccies of the engine bay?

You'd have to ask them, but if you do it yourself all you need is the legendary exhaust spacer. This time it needs making from some 1/2" or 15mm plate and goes twixt turbo and exhaust manifold.

Ideally you want a run on a dyno to see that the MF2 2nd injector controller is working right if you do it yourself.

Oh, you'll need the carb spacer cutting down by about 10mm so the 2nd injector will clear the bonnet, too. I have a small dent from when I missed that.... had to run with the bonnet jacked up at the back until I'd sorted it.

 

[arc]

Had to do that on GeX's 1242 sei too, his indction kit wouldnt clear the strut brace. Apparently its not the easiest thing to machine, its just some sort of resin and turns to dust when u touch it with anything sharp and rotating.

You going to get it dyno'd and set up again aaron? Surely the fueling would need adjusting now? How tollerent are turbo'd centos with altering the boost pressure?

Shame I can't make it to york this year its the same weekend as the international air show, and thats something I help out with every year

I will get some photos of engine up 2moro hopefully.

Yeah I'm trying to get a rolling road session set up soon with Jamie as I'm up that way for 8 weeks on a course, and his car could do with it as well. Fuelling is as you know is controlled by the ECU/Lambda etc and with the 2nd injector it should still be fuelled OK, but there's always room for improvement. Don't know about tolerance when altering boost pressure as I've never tried, but mine is set to 0.6bar of boost but regularly see 0.8bar on initial acceleration. I wouldn't recommend altering a low boost conversion tho as it will definitely lead to detonation, on mine it has low compression pistons to stop this but I think any more boost and the way the TB top is set up would need to change as it has to many areas that would leak boost out defeating the purpose of running more boost. I once saw 0.1bar boost gain on my 5 turbo just by tightening hose clips around the intercooler!

What a beast of an engine just what mine needs shame the insurance company dont agree

whats the 0-60 on that now or havent you tried

 

[arc]

Fuelling is as you know is controlled by the ECU/Lambda etc and with the 2nd injector it should still be fuelled OK

I thought tho that under full throttle, the lambda is ignored and the fueling is determined by the map stored on the eeprom. Meaning it'd be leaning out under full throttle

 

[J333EVO]

Yeah 2nd injector which is a green injector (think Cosworth, integrale etc) so flows lots of fuel which in turn runs off 2nd ECU which will take readings from vacuum/boost and act accordingly, so I'm not worried about it being lean, but as I said everything can be improved on
