Hi,
Have spent 4months and lot's of £ rebuilding my TV8 engine ready to use as our wedding car for 28th May. Engine was running OK (ish) before starting the rebuild but leaking oil, grubby and an unknown quantity having been untouched (apart from oil changes) for 4 years since I bought the car. With rest of the car now restored it was time to tackle the engine and clean up the bay. Block was then bored and honed +40, crank reground, new pistons etc and cylinder heads skimmed new hardened valve seats etc etc. This work all done by Newark Engines and no problems found at all when everything measured and checked.
Engine was then re-assembled on a jig in the garage (taking great care) and then fired up to test, apart from struggling with a few timing niggles etc no major problems noted at this stage. Then it was left for a week before planning to put the engine back in the car. Before starting we made some final checks; there were no leaks at all on the floor but when the oil level was checked it was way up the dipstick...sump nut came off to have a look and at least 1litre of water came out with the oil. You can imagine how we felt!!
So we spent all day Saturday trying to see where the water was getting in, eventually by looking down the shaft where the distributor drive is we can see water running out somewhere half way down the block inside, we think below the oil gallery where the jack shaft runs, from there the water obviously runs straight down into the sump. It's at the back of the engine on the left hand side but checked the head gasket and replaced it to no avail. It's very difficult to see or to understand where the water is coming from, the water pump was rebuilt and the water galleries on the rear of the heads checked too. I'm guessing the block was chemically cleaned and wondering if that process may have dissolved some kind of plug internally? The leak only seems to be obvious when the water system is under pressure but it's not just weeping out...it's trickling and very obvious. Have also ordered an endoscope off ebay to see if we can see better down the shaft.
I'm guessing others may have had a similar issue in the past...any ideas where the problem might lie would be very appreciated!
