Opel Manta A Series steering rack rebuild

Steering rack reconditioning.

August 29, 2018

I think i must have taken just about every part of the Manta apart at some point, except the steering rack! So as the workshop manual has a nice section on the steering rack and an exploded view and i had a spare rack i thought i would have a go at taking mine apart! It was just as well that i did as when i stripped it all down a could see that the internal guide bushes were badly worn. So i pulled these out, cleaned and check the rest of the rack, which all looked good. So then…

Period radio or New?

August 11, 2018

That was a question i kept asking myself. But as the car was way off being finished i never look into it too much. But as we are getting closer i thought it best to do some looking into it. The fits and looks just right as it the twin spindle one which fits the original hole, but its always been rubbish, even when new!! Its only the radio that has been any good. So i looked into trying to get it adapted for an audio input, but no luck. I looked at new “Old style” but they just don’t…

Chevy S10 clutch fitted to Opel Manta A Series

Fitting the Mighty S10 clutch

July 14, 2018

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…

Dipstick alternative option

June 14, 2018

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…

Engine Rebuild

June 13, 2018

So the crank is back after a regrind and is 0.25mm under size. The new bearings and piston have arrived and the bottom end is all back together. Now its time to fit the timing chain cover and other bits.

Fitting Pistons

June 13, 2018

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…

May 24, 2018

FOOT DOWN, LETS GO!

April 7, 2018

Now the winter has finally passed and the nights are longer is full speed and back on the project again 🙂 While i wait for the crank to come back i have a few other things to keep me busy! Today i had a full day on the Opel and as the weather was nice and dry i managed to get quite a lot done. When i removed the engine and box to give that the check over i noticed that the torque tube doughnut looked like it had a crack, and on further investigation noticed it was totally shot! so…

Spring Time = Opel Time

March 8, 2018

So now the bad weather is out of the way and its getting warmer its time to get moving on the car again. I have a new plan of attack to try and get her finished this year! The crank is at the engine shop and needs a slight grind which i think was down to the problems starting her up and getting the oil pumping as a few of the bearing did have wear that looked like they had been short of oil. So hopefully in a couple of weeks, the crank will be back and i can get…
