The 'E' Type Forum

But how many quarts are in the sump? Seems you missed my point about dipstick readings.

To answer your question about the inlet manifold pressurizing the crankcase: No. How would that even happen? the inlet manifold and the airbox are seeing negative pressure when the engine is running. You first need to positively identify the source of the leak before you and all of us on this forum ...

The below photo is from Classic Fabs website. In my case I have their mounts as shown, but my center mufflers have standard style mounting straps with bolts through the strap lugs and through the rubber mounts.

Andy, FWIW-Having owned three E types almost continuously over the last 40 years, I found the factory style center muffler hangers to be a very poor design, prone to failure in shear. The OEM originals were marginal, and the repros available today are much worse. The Classic Fabs style are the way t...

Blocks of wood were not standard. There was originally a spacer (about .25" thick) under each mounting point that sat directly on the floor pan to prevent crushing of the floor covering.

Try it with the distributor removed. I found it much easier to reach in from the front.

Hmm....in the last 50 years or so, I've owned 60 some automobiles and motorcycles that used carburetors. I currently have 6 older cars with 16 carbs between them. I've always checked the metal floats for fuel ingress as everything I read said to do so. And yet I've never experienced a defective/leak...

While I wouldn't say it's not worthwhile, I've had 3 E types (2 3.8, and 1 4.2) and never had an issue with overheating or feeling the need to bleed the last few cc's of air (if in fact it exists) from the intake manifold. Quite possibly it would have value on a competition engine, something about w...

There is a fix for under reading AC tachs-and that is to send it off (to Mike Eck in the US-see the US JagLovers Forum) to be modified to use the tach generator signal as a pulse input. The mod is an internal circuit board, and requires a switched +12v wire to be added. Not other wiring mods, so it ...

A permanent elongation of the stud would be accompanied by a reduction in diameter, however slight. But how did that reduction manifest itself? A consistent reduction along the entire shaft? Near the center of the stud? A reduction of the root diameter of one of the threads? In several places along ...

I run the MWS 6.5" wheels with Michelin XWX 205/70-15", with no clearance issues at all. Rear bump rubbers have been reversed, but not sure that was required. MWS have done their homework on proper backspacing for this application. You do have to have the rear of the car fully lifted to fit/remove t...

1. correct but I would add there is the fast idle adjustment screw used when the choke lever is engaged. 2. If I understand your question, yes, the throttle plates can be tricky to get exactly synchronized due to the inherent free play in the individual drop links from the throttle shaft to carbs. B...

Or just use a deep well 12 pt socket...

If the car is low miles and if the engine has never been seriously overheated then I wouldn't trouble myself with installing the hold down kit. But if the head needs to come off for any reason, or perhaps when it's time to set cam clearance (i.e. cams need to come out) then I might install the kits....

An internet search of "Jaguar BD 35971" brought up a Martin Robey diagram of a Jaguar XJ6. Looks like it's a LH wheel arch panel seal for that car.

Mark,

The oft mentioned torque dip can occur with those awful tubular manifolds with the large fan shaped 3 into 1 collectors on an otherwise stock engine. With the build you are planning it shouldn't be an issue.

positive crankcase ??, do not know what to check with that There is no positive crankcase ventilation system with the 6 cylinder engines. Just a crankcase breather that vents into the airbox, so not a possible cause here. Also, incorrect timing cannot cause such an 1800 rpm idle by itself. I would ...

Well, obviously you're getting extra air from somewhere. An incorrect float level won't cause this. You've checked out all the obvious locations like spindle shafts with propane/starter fluid/etc, yes? And you are clear about the difference between the slow running screws vs the mixture screws, yes?...

Disconnected, and plug the vacuum line to the engine when setting timing at idle. Connected when checking timing advance at various rpms. From a timing standpoint, there is nothing special about the XK engine, other than #1 plug is the one closest to the firewall. Keep that in mind should you ever c...
