what did you pressurise the system with and what pressure did you use as a max ? need to check mine

Will, seen as someone borrowed our pressure testing kit and didn't return it, and i want to test a car this weekend I will make a simple cheap tester after lunch and post a pic in the forum's how to do section.

And IIRC you need to trim the little tabs off the end of the manifold gasket after you've fitted it. otherwise you'll get (potential) oil leaks from the rocker covers.
At least I think that's what you need to do - what do I know, mine's a straight six!! :?

That is very true, Philip.

Yep, once everything is torqued down, run a scalpel along the inlet manifold to head faces at each corner to take off any surplus gasket.

Right, I've been out carrying out some investigation aided and abetted by Richie.

First, we pressured the cooling system and identified a couple of leaks/weeps, no rectified.

I put new spark plugs in (I happen to have a set) and WD40 (well 3 in 1) sprayed around the inlet manifold. No change to engine note.

Inlet manifold bolts check torqued 3 of the took 1/4 if a turn by nothing significant. None of them over-torqued.

Carb off and checked over, no issues. Just for you Phil the gauze is in as good condition as the day I made them :wink:

Inlet manifold off and I think we have a winner. In our opinion there is evidence of oil/water getting where it shouldn't and the passenger side looked worse than the drivers.

New gaskets already ordered from burton power, oil flush and change will be done as we spilt some water into the engine when we lifted the manifold off.

I use one of these, I managed to pick one up cheap a few years ago. i can't remember what pressure we tested to, I was expecting a leak so when we got on after a few pumps i was happy and fixed the leak.

A bit of progress today. Richie and I have it back together. We put the inlet manifold back on with a new gasket, thermostat housing flattened and fitted with new gasket same for the fuel pump (it had a small oil leak). New carb gasket and lid gasket (lid had been on and off a few times) dizzy back in. Dropped the oil and water out and refilled. Primed the carb with fuel and blow me if it didn't fire straight up.

The timing needed a minor adjustment, we identified a couple of dodgy leads using the strobe light.

It revs ok, there was some blue smoke from the left side which cleared. I very quick test drive proved that there is still a problem with the brakes (no surprise) it runs/pulls better. But it's still not right, still missing on the left side under load. We are hoping (probably wishful thinking) that there is some crud in number 6 which will clear after an Italian tune up, there was a build up on the spark plug.

I'm ordering new leads to rule them out. I've exhausted my brownie points with Mrs Gillsfan, so I'm staying out of the garage for a few days.

I'm on to thinking about the brake servo. It seems a 2nd one has failed. The 2nd hand Lockheed that Jim kindly swapped for the original failed Girling, seems to have failed during my ill-fated test drive to Macdonalds. The obvious fix is to replace or repair the servo (again), I'm slightly reluctant as I'm worried I'll break another one. Any ideas what could be happening or I'm I just unlucky.

Are these repair kits A the right one and B any good?

I'm very reluctant to buy a new one as I'm worried it'll fail again, I may plump for a used one again.

Maybe just while your getting it up and running bypass the remote servo?

I'd be tending to avoid used ones - the internal condition is unknown and may fail at any time . . . . Brakes are important to be reliable, after all :shock:

Have you bypassed it to check yet?

Why would a new one fail more then a used one ?

It's not that is more likely to fail, I'm more concerned that'll ill spend out on a new one and I've got a fault that is breaking them. I'm leaning towards bypassing it as JC suggested and getting a refurb kit for the one I have.

Jim I haven't yet, but I will. I feels the same as last time.

So new leads fitted and timing set again and card tuned. Running better but I have a back fire and a flat spot at 3000 rpm. Video of back fire is on the following link.

So more to add, I've checked the vacuum advance by sucking the tube and it moved so I'm assuming that works. I checked the timing and in the 1/4 mile test drive, it had moved. Reset it and revved the engine, check again and it had moved again. Taking each lead off, in turn, showed that there was no change in engine note when 3 or 6 were removed, but both had a spark. More videos on the link in the previous post, sorry I can't seem to load videos to scimitar web.
