Manta A with problems

Recommended Posts

I have a lot of work with my own cars but sometimes they are less important cause I want to help a friend.

The Manta-A had a red warning light (oil pressure) but the driver kept on driving so I had a panic-call for help.

This was some time back and I took pics for the valuation report.

Engine and gearbox out,

This looks bad, the 1.9s engine is dead. Somebody putted a 1.9N carb on it and the car looks pretty good so I have a 2.0E engine 

that was originally of the GSI.

Cause the engine is too heavy to get it out of my garage I carried it in parts out. Think a lot of us have that corner in our yard with 

stuff that is waiting to get out.

I used the original head again, the car runs on LPG but the valves looked ok, just cleaning and grinding

Some saw it, the original 1.9S engine is the old type, with the flat oil pump plate. So the valve stems have no seals. 

Checked the valve guides and stems and they were in tolorance. Cause the owner complained the engine had some 

oil consumption I milled the outside of the stem-guides so seals would fit:

Next thing is putting a tube in the head where the oil goes back in the engine, so the oil-level will be higher and the camshaft 

is better lubricated:

Hi Ian, thanks for the kind words. Yes if you are a car mecanical you have a lot of friends!

So we will complete this story:

Naked VIN-plate, was missing on this car so I ordered it at "Splendid-parts" in Germany:

The gearbox: I wanted to put a 5-gear getrag in the car but my friend wanted the car original.

No problemo, so new gaskets and some springs, the gear shifter works like new again:

New gaskets for the engine, original Opel. They are getting rare:

And making a new gear-box silentblock. Don't say this further; this silent block is from a Leopard Heavy Fighting Tank...

Next thing to do: The steering column:

Don't hit the centre of the steering column with a hammer to loosen the steering wheel! 

If you do this you can have this problem:

the new bearing is the one with the bronce outside, the original one is in pieces...

Thanks, going to show the last pics,

The seat is out so it is easyer to work in the car:

The key didn't turn nice in the lock, so I took it out:

Noticed there was a lot of dirt from old oil etc. between the small blades:

Before you do this make sure you don't mix the blades, otherwise your key won't fit anymore:

And the last project is the repair of the start-engine. The fork was worn, you all can see those two "fingers" that move the bendix

are halfway disapeared. But those parts are still available at our local car electrcity shop. Wasn't in stock but had to order it.

That starter is from 1972! So don't throw it in the binn, repairable!

The car is at this moment back to his owner, the spring is opening the season for nice trips with it.

Love seeing a car being “repaired” instead of replacing parts. 10 more points for using parts off a tank!

Herman, I said it earlier and I will say it again: what a great friend you are!

Fantastic work on a great looking car.

Your work on the lock barrel has reminded me that I may need to do something similar on my boot lock soon.

Nice work! I need to replace the bearings in my a series steering column too. Is it a big job to get the ignition barrel, signal stalk etc, off? I was a bit scared off by the Haynes manual talking about shear bolts etc. In practice, how big a job is it?

I expected also those shear bolts. A Manta B has got even one where the column is bolted to the fire-wall. This A had an normal bolt.

If you notice the steering-lock has got also a shear-bolt it will be easyer to built the column out and drill the bolt out when your 

collumn is in a vise.

Don't remember I had diffuculties whit taking the elek. parts out of the collmn, but I remember I tryed when everything was apart if the 

new bearing slided easy over the shaft, and I used the outside shell of the old bearing to fit the new bearing. Normal there is a Opel-tool 

but who has got that tool?? 

The plastic bearing on the bottom side was still in good condition, I remember there was something with a spring...

First make sure you find a new top bearing. I looked for the partnr. and Opel still uses those bearings on a lot of modern cars, even Camaro (GM)

has got the same one. But at Opel they were out of stock so I ordered one at Dr. Manta in Germany. 

Succes with the replacement!

Removed sheer bolts by removing 1/3 of the bolt head on left, and 1/3 on right. With an angle grinder.

This way you are left with two straight edges to grip with vise grips, 

Hope this makes sense, pictures paint 1000 words! No pic, sorry!
