Close, but no cigar!!

After a very long day on Wednesday taking the car up to Northampton Motorsport, we are so very close, but still not there just yet!     Some good news, and some bad news! The car fired up first turn and ran which was great to see 🙂 but then there seemed to be a few issues with the Webcon setup. The first was number 1 cylinder was not firing so the engine was stopped and the plug swapped, then the fuel pump would not run? noting wrong with the pump it turns out, so something wrong with the loom…

GM/Opel CIH Engine Timing Chain Guides & Potential Problems

Im writing this little post on some of this issues i have encountered when building my Opel Manta CIH engine due to the differences between the Original GM/OPEL timing chain guides and the aftermarket ones. It started off with me finding it very hard to fit the top chain sprocket onto the cam end and thinking was it the aftermarket chain? or the banana guide?, so sourced an original chain and the long guide. The banana one does not seem to be available as an original one only aftermarket ones, but i did find an original one for the chain…

Cylinder Head Rebuild

If you happen to pass by my blog every now and then you will see that i have not posted for a while, mainly because if have not been up to much on the Manta. After hassling the engine builder to get the cam bearings in and the head back to me, i got the head back and was ready to build up the head and then i got side tracked into trying to sort out my Seat Altea as just a week before the MOT was up the passengers door lock would not release the deadlock. So weeks of…

Chevy S10 clutch fitted to Opel Manta A Series
CIH Engine, Clutch

Fitting the Mighty S10 clutch

I had always wanted to fit a bigger clutch, just to be on the safe side. So when i had the chance to get an S10 clutch from Opel GT Source in the US, i took the chance a bought one (I was lucky enough to have someone bring it over from the US as the postage would have been more than the clutch!) and thought one day i will fit it to the car. But as i had to have the engine out to sort out the piston i thought now was the perfect time. Using the Monza flywheel…

Opel CIH oil pan dipstick alternative option using Ford 7.3 V8 pan adaptor

Dipstick alternative option

Not wanting to have to drill the block to locate the dipstick hole where it should be for the manta in the block, i did a bit of searching and found the the US Ford 73L V8 Diesel has an oil pan dipstick!! So after a bit of measuring and checking i reckoned that this would be just what i needed. So i ordered one on ebay and when it arrived measured it and bought a metal hole punch to cut a nice clean hole and as i has a spare oil pan i thought i would give it a…

ring compressor sleeves from Wiseco

Fitting Pistons

Last time i built the engine up i used one of those pesky band type piston ring clamps and it wasn’t the greatest thing for fitting them. So this time i did a bit of reading and came across these ring compressor sleeves from Wiseco. They start off wider and taper to the same size as the piston bore. So i bought one to try it out and they are Amazing. No hitting the piston top with a hammer end or something like this. These you can just push in with your fingers as unlike the band type that you…

Engine out

Ok, it’s been a while since i posted and also since i did much to the old A series! Life kind of gets in the way far too often!! So as i decided to fit the S10 clutch and new flywheel i decided it was time to fix a couple of bits i was not happy about and as i like to do things big style! it was engine and box out. So i now have the box and engine completely out, the front suspension and part of the exhaust. So things to fix: Manifold – drill out holes as they…
