timing cover crankcase oil seal

[bootlid]

would now like to remove timing chain cover to replace curved rope crankcase seal,bottom curved seal on sump did not stop oil leaks when renewed,any advice after radiator is out would be appreciated,is it straight forward job or have many problems,at present three runs of oil running down sump as far as gearbox.

You will obviously have to support the engine as the mounts are on the timing chain cover.
Never tried replacing the seals with the engine in the car but here goes. First I will go through how I would do the job with the engine out of the car and then try to work out a method of achieving the same results with the engine in.
With the sump and timing cover off, fit the new seals, oil them and put the sump and cover together. Put the crankshaft pulley between the seals then tighten the sump and cover together, turning the pulley until it is tight, Slacken, add more oil and tighten, Leave to bed in overnight. Take care not to fray the ends of the rope seals. Keep tightening until thesump and cover are secure. Strip down and reassemble on the engine.
With the engine in the car the problem is supporting the engine when the mounts are undone. It is getting late so I will think about that problem

job now done mike,sump not required to come off,only difficulty getting the pulley back on as kept fouling rope seal but managed after some effort,was going to replace timing chain but decided not to as no removeable links on both chains would have meant very difficult job ahead,attempting to remove chrome grill now but also very difficult job,have to remove starting handle guide and hacksaw through radiator support in order to remove grill.

I hope that solves the problem. My concern was damaging the seal when replacing the crankshaft pulley, I think that I would have slackened off the sump bolts and let it hang whilst replacing the seal and pulley, and slackening the timng cover also

The person doing the job is pretty good with morris cars,he has three sidevalve engine types,the timing chain seal kept moving downwards causing the pulley to jam,we kept pushing the seal up with a flat screwdriver and were lucky after a few goes to get the pulley to slide in,i also do hope thats the end of the leak too,pre3tty frustrating leaks in old cars,thanksn mike..

Car tested recently and oil leak still persists,after making enquiries i found out that the person who fitted the timing case back on has admitted that the oil thrower is missing and so i will have to look for an oil thrower for a sidevalve engine,how essential is this oil thrower to stopping an oil leak.??.

The oil thrower stops direct oil splash against the seal so it's pretty important.

You can machine out the timing cover & sump to take a modern oil seal. It works well.

I am presently taking instruction to try something differant as my engine has an oil thrower which does,nt appear to be doing any good,i,m attempting to fit an m.g. 1275 engine rubber front seals soaked in a special sealant as i,ve practically give up sealing my disasterous front sump/crankcase oil run,i could never drive this car at present as losing too much oil.
