Well that was a long job, really hot out here today.

Checked and cleaned every electrical connection, reseated all the injectors, changed the plugs back to Bosch Super 4's, blanked the EGR valve. Takes ages with all three pieces of the manifold - stupid egr pipe lol

Did find three air leaks / suspect or broken gaskets, EGR, Idler and throttle body - used the faithful black sealant. Cured the coolant leak, why do they fit those stupid spring-clips on hoses...jubilee clips are much better.

Well certainly sounds and feels different tickover is throater and sound like a muscle car ticking over with the air-con on and is more responsive - think I will have an emissions test before the mot as I still wonder if I damaged the cat.

Sounds like you got loads done mate. See how the next few days go, but it all sounds positive.

Took the lady for a drive this morning - but didn't push her, engine seems a lot more responsive, does sounds different - more grunt and no worrying engine noise, however the engine management came on - but no loss in power or was the car put into limp-home mode. I am thinking it isn't anything sensor/timing related but is either because the EGR is now blanked or because the weather is a lot warmer and too much hot-air being drawn in (engine bay)its time for me to remove the open air filter, refit the std airbox - which is the norm during hot weather with V6's, a visit to the garage after school run tomorrow morning will reveal all.

So a bit more upbeat about her now

Sorted, ECU has been through its cycle and warning light is off, so that was down to the EGR blanking. Tomorrow I will refit the Courtneys air box and hopefully thats that

The work I did yesterday has certainly transformed the engine, - tickover, sound etc

I'm really glad mate. It sounds like your problem was vacuum hosing, among other things. But the fact its noticably different, even in our stupidly hot weather for this time of year suggests a huge change.

In the hot it should be the other way around, so clearly you were down some power! On V6s, the cone air filter is just for noise, the engine bay is far too hot for any performance gains etc unless your thumping along and getting airflow in the front grilles. Most of the best V6 engines all use standard airboxes for this reason. With the heat that engine generates it really is the best option.

I totally agree, and there's a large majority of V6 owners who also agree, besides with a twin cat-back exhaust it has a nice grunt, so I loose the induction whistle lol.

I had a alluminium heat sink made that screws to the chassis plus the filter shield, yeah it sounds good lol The garage owner where I take the car said the bhp gain is minus figures this weather and he also said when the engine is at norm temp, so I usually switch to sealed in the summer. This morning both shields were untouchable....hot!!! So unless I am moving at a reasonable speed any air drawn in will be hot.

The courtenay box (I picked up from a written-off Vec for £5) has a larger inlet than std - same external size and the old owner had a reducer pipe fitted fed from the three pipe.
I also have the K&N panel not the foam filter, so I can always add the cold feed pipe from either behind the Opel badge (OPC grill) or n/s/f of lower bumper.

Thinking about the add-on's since the last time I used a sealed box as we had a mild summer last year..., 3.8bar FPR and the EGR wasn't blanked, so I should see an improvement plus what I did Saturday with the airleaks and connections.
