Engine rebuild question

28 Mar 2012, 7:19pm
Hi Andy,
no,sorry no results yet. Due to other commitments, I've not got my car back on the road yet and it is still SORN'd. I plan to get it taxed from the 1st of April so should then be able to do some proper road testing. I'll let you know when I've got some results but I guess the real test will be later in the year when we get some high summer temperatures.

In the meantime, here is a picture of my header tank. I ended up raising the tank by 35mm and dropping the radiator by about 15mm. The top of the radiator is now level with the 'high' mark on my tank.

Hi Peter, is that the header tank Marlin provide with Module 2 or one you sourced separately?

Hi Ian,
I sourced this header tank myself as I wanted to mimic the BMW config as close as possible. (The Marlin supplied tank was very small and didn't hold the same volume of coolant nor much expansion volume. But I should point out that I had no evidence it wouldn't work though).
The tank I used is a Ford component but I don't know which car/application. I noticed it being used by Westfield on their LSIS's at a kitcar show and it has similar dimensions to the original BMW, so I bought bought one from their on-line shop.
But other builders have successfully re-used the original BMW header tank, so that's another option.

Don,t believe any forecast longer than 5 days, too many variables to be accurate.
Met office are pretty accurate in that period but even the fourth and fifth days may vary.

Never trust a weatherman. My brother is one and he never told the truth as a child. :whistle:

Thanks, Guys.
I am secretly hoping they have got it completely wrong and it will be warm and sunny again! :cool:

peter - have you had a chance to assess the new radiator yet?
I'm running an old 316 rad in mine and it can't really cope with the 325 M50 under the bonnet.
Have seen a few like yours opn ebay for £115 and was after an opinion from someone who's clearly put some thinking into it!

Radiator now fully tested on a 90 mile run in the baking hot weather today.
No issues and it coped well with the heat on the run and in traffic.
