1. The rod is just sitting in a hollow in the engine... not sure how to hook it to the engine because of the difference in how far the throttle has to move and omp can move.

2. Just because they are 1000cc doesnt mean they are always putting in that much.

3. Apologies for the signature size - I never saw any rule about this, even saw some threads where other people did not know the max size. Will update tonight.

...

No ideas on the Vacuum lines?

Thanks

 

1000cc is huuuuuuuge are you kidding me? im amazed your car even idles!!! the problem is even at redline at WOT youre only going to use about 300cc of that 1000cc available. at that low of a duty cycle, youre not running efficiently..

im really confused as to what vacuum lines have been removed to accomadate your older car. well im out for the day

 

The previous owner was setting up for a turbo... then he lost his licence and his folks made him sell the car. Generally he didn't maintain things well, and I don't really know how decent the work done on it was, it seems pretty dodgy.

It idles pretty rough.. runs beautifully over 3000..

The vacuum lines - there are usualy 3 or 4 that run off the upper intake on the side the omp-rod connects to (just above)...

Cheerio,

Paul.

 

Hey H4, just wondering, is your FB Montego Blue Metallic? Even if it isn't, nice color.

 

"BMW Forest Green" is the colour heh, im quite please with it...

....vacuum tubes.... ?

 

since nobody can tell the obvious...

his ACV is blocked off (i.e. no emissions)

Why would he have vac tubes? The only vacuum tubes you should have is for the fuel pressure regulator (the orange solenoid... goes from the UIM to the FPR on the secondary fuel rail.) If you EGR valve is blocked off (cant tell from any pic) then you shouldnt have any vac hoses there either.

Just make sure there are no OPEN vac nipples... get some vac caps from like pep boys or autozone or something. They're pretty damn cheap.

If you still have the thermowax and cold start assist and all that junk on your TB... then you would have vac hoses for that.

Check that out... just don't pay attention to the 6 ports or VDI part of that and you'll be cool.

 

Ok, so my air control valve is blocked off (no air pump, and nothing connected to the cat.... nothing in the cat either heh)..

EGR Valve is near the exhaust manifold is it not? - My exhaust comes straight off the engine down a 3" pipe and out the back... nothing inline for any sort of management... So I'm guessing my Exhaust Gas Recirc valve is blocked off. Where abouts is it, I will have a look after work?

From what I can tell, all the valve nipples have been cut off and filled over... hack job courtesy of previous owner.

Cheers for that site, some good info, will refer to engine tonight and see what I can find out!

Thanks mate,

Paul.

 

OK I got some more photos here to further document the butchering..

Thoughts?

Anything I should be worried about?

Thanks!!

 

First - the P/O was not that bad.
His work may be a little crude but effective.
I'm guessing that at this early stage of a turbo upgrade, he was running pre-mix. So the OMP is not needed at all. It just hasn't been removed yet.
I can't imagine why anyone would weld the UIM to the LIM.

Take it one step at a time. You may be dealing with a "house of cards".
For example, a vac leak may be balancing a rich fuel feed.

 

Yeah ... I'll give him crude.. Plus no documentation or even a heads up on anything about it at all... No reciepts heh.

I have confirmed that the OMP is injecting oil... just not dynamically. What oil should I premix in with the fuel??

I'm stumped on the welding as well... unless it came like that.. perhaps the edge was beaten up bad and had to be welded to seal.

This car is quite a long house of cards... every time I fix something, I break something else... that's how its gonna be for a little while 'til I figure it all out,

cheers for the thoughts,

 

Normally there is play in the pump end of the rod. You can probably just get a rod from the wreckers, or bend up one out of rod...

Well duh. But they are putting in significantly more fuel per injection event then the stock 460CC. That would explain your rough running under 3K and poor idle.

I try to catch as many as I can.

 

I'll look into this, I reckon I'll premix every 2-4 fillups though... Might even get rid of the OMP all together and premix for life! Any recommendations on what kind of oil to premix in?

Mmmm... Is it hard to change the size of these... also just wondering where I may find them It would be nice to be able to sustain a decently slow speed in first/second gear without needing to slip the clutch.

All good now... just under 20k heh.

Cheers,

Paul.
