Merlin Heads

mgbloke · Post by **mgbloke** » Thu Mar 20, 2014 8:09 am

I have now removed the merlin heads and with a dremell and small burr removed the chemical metal that I tried in desperation to solve the leaks with.
With the waterways sealed I put about 30psi in and dipped the heads into water. They both leak in the same area. On one there is no visible sign of a flaw! bubbles seem to exit from nowhere but the Other one I can see a faint dark line about 2mm long where bubbles are coming from.

I am delivering them back to Real Steel today in the hope that they can be fixed permanently by more laser welding.

Fingers crossed.

I plan to re fit the Merlins for a few months while I test and set up my coil over 4 link mumford suspension. Then I will swap over to the TA heads with the new 5.0L short engine.

I have inspected my heads on this matter and I have no real signs that I have this issue..... for as far I can see it, with the heads still in situ.

My heads are from the very first batch they made.

Spoke to Charles at real Steel when I delivered the heads today and he said that it was only 3 pairs of heads that have had this problem. he said that the casting has been slightly modified on the later heads to prevent further problems.
Full credit to Real Steel though as they said that they will cover the cost of the laser welding.

Ha Ha!!
That's so good of them eh ? To cover the cost of repairing their own faulty goods

I have used RS for many years and the service is pretty darn good. But when I paid £1300 for a new gearbox that broke in just 50 miles of road use I got some bullshit answer that race parts have no warranty ?
I took this up with Charles directly and although it took 3 months to resolve the issue in which time I had to buy another £1300 box I ended up with a spare when the broken box was returned rebuilt FOC.

At least they repaired it, I had an new engine and box fitted by A V8 tuning company, when I got the car off them, it had a gear selection problem and an oil leak. I sent the car back, they had it for 4 months and when I got it back, It still leaked and still had a gear selection problem. All they done was wipe oil off the block.
Great service.

mgbloke,

Just donate them to us, we don't run water anyway

Soon see what the clocks have to say about their effectiveness!

If they turn out to be un repairable you can have them!

Like all racers, all offers are gratefully received, I hope the repair works, but if not will be very happy to see what they can do!!

No more leaks, TA heads and new engine ready so Merlins are on ebay.
