silicon sealants
« on: 07 January 2011, 00:50:15 »
Been having problems with the oil pressure light flickering on her Smart.
I finally got a round to removing the sump pan today to have a look.
It looks like someone has used a sealant similar to Vx's black by the bucket load. Trouble is, some of it found its way into the oil pick-up tube.



and this lump too


which is probably why the filter was collapsing  under the pump's suction. This has only ben in the car for around 3000 miles.


Hence my previous question re cure times for the grey sealant  ;)

I would of thought the filter was collapsing due to being clogged up.

Filter should be on the pressurised side (that way they can use a finer grade filter medium and give much better filtering and is the standard approach) so should not be affected by a blocked pickup.

The oil & filter had only been in for a couple or 3 thousand miles, and the rest of the isides looks fairly clean, no buid up of crud.
You could very well be right, I'll have another look as I build it up today - it's trying to bl00dy snow though  :o - but the pick-up tube does look to be more or less opposite the filter housing  :-/ :-/
Anyway, a load of silcon on the strainer isn't going to help oil pressure  :y

Better there than clogging an oilway! Looks like the strainer was doing its job.  :y

It's not from factory as you can see marks on the sealing face of the steel sump where a medium sized screwdriver has been drifted in to remove it some time previous. Fortunately the ally block seems to have survived unscathed. You'd think a garage would have had a nice broad flat scraper/chisel like mine to remove it.  ;)

They probably have but it might not have been within the mechanics reach and would have meant him moving to get it ::) ;D

Probably more like it  ;D. But if you could see the state of my garage it's a wonder I knew where mine was.  ::)

No surprise that the oil pressure light flickering at idle when warm is now sorted.  :y And although not perfect, it sounds a lot quieter around the cam chain, the tensioner is hydraulic so is now presumably get enough oil to do its job.  :y :y
