There's bound to be a fair bit in there,
And for that reason on a couple of my cars with steel exhausts I've drilled a tiny hole at the lowest point of the silencer box, to allow any residual water to dribble out. Not a big enough hole to make any noise or cause the MoT tester any angst, but enough to allow water to dribble out,even slowly. I thought that was better than it sitting there rotting out my exhaust for months on end.
You may care to do the same?
Cheers!
Some people are like Slinkies - they serve no useful purpose, but they still bring a smile to your face when you push them downstairs.
I think i.might do.that. the exausts i got on a the twin falcon.system and the boxes are arranged vertically so.they could have water in half of them. i will.get tiny drill oit
Well after draining a lot of water from the exaust system the white smoke has all but gone. however there seems to be a reasonable amount of smoke in reving and on full throttle. although i there is still to.much. upon removjng plugs there was oil on them nut they were not black.with burnt oil. quest i was going.to ask.was the oild is rather old in the engine . so how old is to old. ?
Until you've had a chance to give it a proper, long test drive on the road to get everything cleaned up and running smoothly, it is impossible to assess the state of the engine. Give it new plugs, new air filter, fresh oil and filter and a thorough run and then see what is happening.
Remember that the MOT will only require "no visible smoke at idle".
Interesting about amoke at mot. i have virtually no.smoke at idel now so thats not.bad, its just when i rev i get lots of.smoke. i will change oil and filters etc and then see what happens. in the rebuild i have not changed anything on the engine in the way of.consumables so this will be a chance. i do agree though hnless the engine is run for a substantial.while how can any assessment be made. also without a carb mixture.setup being done alot of amoke could.be attributed to incorrect fuel air mixture.
Gling to drain and flush engine today and replace with a good.quality classic.oil and put.in new filter etc.
You'd only fail on black smoke (rich mixture). Contrary to how some testers do it, blue oil smoke and white water vapour aren't grounds for a knockback.
If it's clean at idle but then emits blue when you blip the throttles, chances are you've nothing serious to worry about, that'll most likely be worn valve guides if it's severe. When there's only a slight amount of blue, chances are this is normal as the Daimler hemi wasn't equipped with stem seals, relying instead on decent manufacturing tolerances to achieve something close to a seal.
It is possible to retro-fit stem seals to the hemi, Harley Evo ones will fit if modified with a groove to take a washer that'll sit under the springs, or use "top hat" Reliant 750 seals - the green ones - that are kept in place entirely by the springs so need no grooves.
Oil consumption on the hemi only need be cause for concern when it goes beyond around 200 miles per pint or thereabouts, according to a guy at work who runs a modified SP250. They tend to use oil and that's the nature of the beast.
J "Home is where you park it", so the saying goes. That may yet come true..
Many thanks for the information. it is certainly.nlt.producing any black.smoke at all, just a lot of white / grey smoke.
There was oil on the spark plugs but then again that could be caused by alot of.reasons.
The omly thing that concerns.me is that on sunday i did push the engine a bit on one occasion and got a very large clouse of grey smoke. but as everyone has said without a decent run the engine has not has time to clean out.
For an older engine would it be likely to have oil.on plugs anyway?
After idling for a while with oil being drawn into the combustion chambers in the absence of stem seals yes, a little oil on the plugs wouldn't concern me greatly - as long as the plugs are dry and evenly coloured relative to each other when you pull them after a longer run.
These engines are known for using oil in rather larger quantities than would be expected in its American or Anglo-Swedish counterparts of the period, it's something that classic-friendly MOT testers should know.
J "Home is where you park it", so the saying goes. That may yet come true..
many thanks for thie info. as the car has not been on a long run its hard.to confirm the oil will be moved off the end of the plugs. what does concern me is the smoke on reving which is a large amount. even with an engine that has not been used jn anger in nearly 12 years there was a lot of it. . new oil tomorrow thought.
Does anyone.know.is the drain plug a left or.right thread on these engines
