Hot Start Issues

[B-Reight]

Hi all, wonder if anyone can shed any light on a problem i've been having this past week.

Car starts fine from cold, but if i try to start it after say 5mins after shutting off (like everytime i've stopped for petrol) the starter will either turnover very slowly or will turnover a couple if times and then make a sort of grinding sound. It will catch and start up though. Leaving it longer after shutting off and it starts no problem.

It sounds like the starter motor has 'fried' the only solution is a replacement or possible rebuild.
The right hand exhaust manifold runs very close to the starter and over a period of time cooks the starter, possible remedy is to fit an 'insulator wrap' around the starter.

Check the condition of the cables / connections to the starter as per earlier comments , they break down due to heat from the manifold

My experience is as Cheddar says, the motor can't stand that heat, and eventually just turns very slowly. Mine finally expired amidst acrid smoke, fortunately in a petrol station just up the road from my house.

I fabricated an alloy heat shield and a thermal blanket arrangement to protect the new one.

whatever job you do,,,,you're wasted.

I had that problem particuarly when stopping for fuel. Normal when cold but would hardly crank over when hot. I replaced the starter and it was better but not quite right. I eventually found the earth lead from the battery was corroded badly on the inside. Initially I thought I had wasted the money on the starter but it was right to have replaced both.

A fire blanket is a very cheap solution if you have an old old lying around. There are also proper starter motor heat shields around.

Heatshield made from a sheet of aluminium under the starter, and a sheet of foil-backed heat resistant cloth which I made the filling in a sandwich of steel mesh, wrapped around the manifold and secured with steel ties. The manifold was virtually touching the starter. I have used thermal bandage wrap around exhaust pipework before (mild steel) and never again - it seems to promote corrosion at an alarming rate for some reason.
