New Cam Bearings Or Not


Best Answer Project_1275_GT , Today, 11:44 AM

I bought a part of Andrew about 18 months ago .. and had no problems, but as you say anything could have happened in the time since. His website seems to be still up and working so he's obviously paying the bills for his ISP ..

 

With ebay you have more chance of being fleeced ..

 

We've had some fun & games recently with a seller who kept appearing suddenly selling over 200 vehicles .. all at weird prices and when you checked, publicising a different email and tel no as an image (which is again ebay rules) .. but the reason we knew he was dodgy was the images of two or three Austins we knew WEREN'T for sale .. on one we contacted the "seller" and she advised us her account had been hacked .. but as soon as we got ebay to take them down, they reappeared. I think we were well into double-figures by the time he gave up! (but we are still on the look-out!)

 

As i say im confused. Im constantly checking ebay for parts i still need as I intend as original build as possible. But some of the things on there are shocking. Cars as you say that seem to appear at stupid cheap money and are clearly a con in some fashion or log books for sale. I think i will mark this thread as solved now and just continue with the project thread for the car. Thats as soon as mini spares delivery arrives and all other parts needed. still difficult to find some bits.

 

Thanks for all feed back on this issue.

Not an engine expert. First real engine build at the min. Had some work done on my short engine and should have had new cam bearings fitted. Do these look new?? I understand sometimes they need to be scraped to remove high spots but these look original with wear? Or am i just being stupid? 

 

Any opinions welcome...

They are the old ones, but condition-wise they should be fine.

As i am no expert is there a correct clearance for cam to bearing? 

 

The annoying part is i paid to have a lot of work done and when i have started to complete the build im finding many parts that are not as they should be - 

 

Timing chain should have been IWIS - checked and its ROLON and does not look good. 

Cam followers should have been ISKY - these have no oil hole and look like mini spares basic version or original, i just dont know

Cam bearings should have been replaced and have not been 

Pushrods replaced and checked - found 2 so badly bent i can not believe anyone would fit them

Rocker studs should have been replaced - these are bent and old

Head studs and nuts should have been replaced - studs new but quality unknown and old nuts 

 

Im now very concerned about the crank work and pistons that were also done. I now have to strip everything to inspect. This is not what i need. I should have been completing the engine this week.

It Is no consolation now, but with Engines no longer cheap throw away items and the days of getting them bored for a "drink" over you really need to go to someone recommended and trusted.

 

A lot of engineering shops have gone since the 90s and "jobs" done correctly are no longer cheap, and any that are cheap you soon discover why.

 

Most of us now, due to the cost prob wont have many engines built so it needs to be right first time and as minis are now not often daily users its best to wait save up the pennies and get it done right the first time.rather than rush it.

 

I would now only use trusted shops who have a reputation to lose

This was my original thoughts. I posted on here last year requesting for reputable people that could do the work. The guy that did the work is a member on here. Has his own website for mini parts and has worked with minis since 1979.. He seemed genuine and i paid good money for this work. It was not a cheap job. I have all details of agreed work agreed and now what i find is poor quality, half done, cheap parts.

Just been into the garage and striped crank bearing caps to check if the bearings have been replaced as agreed. Again i am no engine expert. These look original.

They are certainly not new bearing shells but - more interestingly - all three caps have a centre retaining notch, which is what you would expect on an A plus engine (apart from the very early ones) and those are pre-A plus shells. It's obvious because of the oil groove, the A plus are plain, no oil groove, to carry a higher load.

 

It's a common trick to cut a centre retaining notch on earlier engines to be able to fit the later shells but that looks like the opposite has been done, a side notch cut to fit some second hand early shells.

 

Also, in the photo of all three, if they are laid out in the orientation they came of, the middle is probably on the wrong way around.

 

What year is the engine? ie is it an A-Plus? (a slim possibility is that it's a pre-A plus that has been modified to take the later shells but they've not been used in this case)

The engine is A + metro turbo engine. The caps are laid out in order / orientation as removed.

Well, unless it is a very early A-Plus engine, those are pre-A plus bearing shells.

 

The very early A-plus engines did still use the grooved bottom shells - they are rare but I have one - but all of the A-Plus, apart from the very early ones, had plain bottom shells.

 

In your photos you can see the "notch" in the middle of the bearing caps which is where the tang for the A-Plus bearings would fit.

 

Pull the shells out and see if the groove/notch where the bearing tang sits on yours looks milled by the factory or just filed/ground by someone.

 

As for the cap order, the notch should be on the same side for all three.

I have now managed to speak with the guy who did the work. He apologises and can not explain how these issues arose. I have listed the parts that are not as specified and he promises to arrange parts for me this week for delivery. He did offer to take the engine back and do the work but I see no point. I will complete the work myself. I may be asking some questions later in the week. 

 

I have added some pictures with the shell removed.

Does this look correct?

No, not at all.

 

There should only be one notch, off to the side for older A series (and very early A-Plus) and in the centre for most A-Plus. And the bearing shells would be plain for A-Plus (no groove).

 

It looks like someone has cut the extra notch to fit the older bearings to a more recent block.

 

Presumably just to use old,second hand bearing shells ???

 

Kind of sad if the person claimed they knew what they were doing and made you pay for it.

I have contacted the guy that did the work and he can not explain why work was not done as agreed. I have given him the list of parts that are not done correctly and he has said these will be posted to me this week. It is quite a list that I am not happy with. But he did offer to have the engine back to do the work. To me its very concerning. Most people that pay for half engine build would not strip it again before use. I took some parts off to allow painting, then removed a few more due to the first bits not being correct. Now its almost bare again and will have to be fully re built. This was not my plan. Or what i paid for

To be slightly fair to the guy, if its a big operation, and engine is only as good as the actual guy who did the build. If its a one man operation though then there are no excuses whatsoever.

 

Would it be worth letting him "rebuild" it, again then checking it when you get it back.?
