Exhaust - Lack of cleaance

[John Larkin]

I fitted a new stainless steel exhaust from P D Gough Ltd to my 1974 P6B automatic last year. I was unable to attach a u-clamp to the joint on the right-hand downpipe where it passes under the sump because of lack of clearance (about 5mm available). I blew the original engine in 1990 and it was rebuilt using a P5B block. After discussions with P D Gough Ltd about the problem it seemed that the probable cause was that the P5B exhaust manifolds were used on the re-built engine instead of the P6B units --- apparently the P5B manifolds are shorter vertically than those in the P6B. Last week I had the exhaust manifolds replaced with a pair taken from a scrapped P6 VIP, but I still have the problem. Has anyone experienced a similar problem with P D Gough exhausts? Another possibility is that the sump is not from a P6B. Can anyone tell me the correct depth for the shallow bit of the P6B sump --- i.e. the dimension from bottom face of the block to the underside of the shallow section of the sump?

On my sump the shallow section at the rear of the sump is 2 1/2 inches deep although it does slope slightly and increase to approx 3" near the step down for the pan. This sump is an original p6 auto item but the has been fitted into manual car with no clearance problems (I presume they are the same)

Incidentally I had a complete stainless system made AND fitted by ASCAR exhausts in sheffield for about £300 and was very pleased with the work. I decided to have it made and fitted after problems with an on off the shelf system for another car that had to be sent back as even the individual sections of the twim pipe system would not fit together!

Thanks BBLongman. I'll measure my sump and see how deep it is.

BB, could you please give some contact details for ASCAR in Sheffield as I need an exhaust for my 3500S soon and I was thinking of a stainless one.

BTW, does anyone know if P D Gough supply and fit if you go to them?

Cheers

Hi Nick

ASCAR's phone no is 0114 2722440 ask for Phil Jarvis. They advertise in practical classics by the way. I also had a mild steel system from them a few years ago on a saloon and that was v cheap at £150 fitted!!

HI,

PD Gough will fit if you visit them, but you have to book in advance. They charged me £50 for fitting on a full system.
