Can anyone identify this tapping noise?

This issue with the spun bearings interests me and I've watched the LR vids about Fabian's engine.

Bit of background............. in the early 80's I was re-coing a VW 1500 type 3 engine with expert advice from my grandfather

Everything necessary was done and I bolted the 2 crankcase halves together and torqued to spec. Couldn't turn the crank by hand. Split it and GF had a look and could see that one side of one of the 'caps' in the middle of the case had been hammering.

To get it line bored in those days was $430, which was a lot then. GF said no need and scrounged up some shim steel from a local bloke, cut it to size with scissors, used a hole punch where the bolt went through and it got put back together and all was great for years till I sold it.

Couple of things about the LR Time vids........ where he has the case upside down and has taken the cap bolts out he seems surprised how easily the centre caps lift out.

Next is where he line bores the block with the caps on and he's only removing material from the caps.............suggests to me that he's skimmed the mating surface of the caps where they mate with the block (which I don't remember in the vid) or the caps have been hammering away in the block due bolt stretch or incorrect torque............. and the bearings have spun.

Garry's post is the first time I've read of loose caps in these LR engines.

To get to it you need to remove the second sump, not just the oil sump, so it’s not a simple task. A few things need to be removed to gain access but it will confirm the diagnosis.

Assuming you get to remove the engine, try and find the build date on the failed engine (may be on side of block behind alternator or will be stamped on end of the crankshaft).

Personally I would buy another RRS (perhaps get a V8), then part out your current one to recover losses.

Cheers mate I'll defiantly have a look at the V8's

If it were me I would want to know it was definitely spun bearings before spending $15k (engine and labour at its cheapest) on getting a new engine - I would even consider taking the engine out and checking - afterall if it is spun bearings the engine has got to come out anyway.

In addition, when you took the sump off, did you see any metal in there, likewise was any in the oil?

Cheers for that, When i took off the sump I couldn't see any metal just about 6 or 7 copper specks, ran a magnet through the
oil and nothing! might be different now though looking at the second oil filter after the flush with heaps of metal filings through it!

Thanks Discojeffster,

I will remove the sump again and see if i can get to the second sump, nothing to lose!

Cheers

I keep dreaming of a Supercharged 5L….would be the perfect way to see the fossil fuel era off. The last of the great V8’s. TdV8 would be my second choice.

Nice! yeah they sound great!

This is mine, pity its only a 2.7, or was!!RRS1.jpg RRS2.jpg
Looking at the receipts, looks like its had two Tranny rebuilds also

Black lemon??!

Magnet isn't much use, bearings are white metal and copper, bigger problems if the crank is shedding metal fragments.
Since the motor still runs it's a good candidate for a rebuild.
