Cam timing info

CIH Cam and Ignition Timing  Originally Posted by GTJIM . . . Timing the cam is one of Opels little endearing foibles! Even the Factory Service Manuals cam be misleading as the drawing of the engine is actually WRONG in some of them – nice huh! Fortunately the picture of the crankshaft keyway position and the text is correct. The keyway in the crankshaftMUST face upwards and #4 cylinder be at Top Dead Centre with the camshaft turned so that the valves for #4 cylinder are closed ( the cut outs in the cam for access to the head bolts will be in the correct position as this setting). Once the cam wheel is…

Manifold all painted and ready to go back on.

When i went to have the car tuned it was clear that there were a few issues with the manifold not seating properly so i took it off and had the face machined flat and while i was there i thought it would be a good idea to get the manifold painted at the same time. I was going to just get a can of high temp paint and do it but as usual, after a bit of reading up on the best paint i came across quite a few reviews for POR15 High Temp Heat-Resistant Paint that were very…

The Countdown Begins!

I have taken the decision to take the Opel up to a proper tuning company in Northampton (Northampton Motorsport) to do the initial start-up and then all being ok the set up so the car is ready to be run in.

That is planned in fro the start of October so i now have just over a month to do the last final setup on the cam, fill up with break-in oil, check that everything is all tightened up properly and get the brakes and clutch…

Hydraulic clutch fitting on the Opel manta A series

I have always hated the clutch cable crossing over the engine on the a series and wanted to get rid of it and fit a hydraulic clutch, but have found it hard to find any info on someone fitting one. So i did a google and looked at other cars using the wilwood pull cylinder to get some ideas. I decided on an external slave cylinder as its such a pain to drop the 5 speed gearbox on the A if i did have issues. So a plan was hatched. i decided a bracked that bolted to the engine and…

BMW Halo Angel Eyes now all working in the Manta A

Once i had figured out the A series wiriring it was a quoick and simple job to get the lights all working. They work just as the A series ones use to. I cant decide if i should hook up the Halo’s to run as soon as the ignition is turned on so they are like running lights? It should be as easy as swapping a feed out from the ignition to the light switch. But as i have a few other more important things to sort out first so i will leave them as they are and add this to…
