Mayo in my engine

[flyerncle]

Vent it to the tank as it may well just curculate and not vent and make sure the tank vents to air as well or fit a vent to the block with some sort of filter.

Ok, I,ll try that then, I,ll put the crankcase vent direct to the catch tank ( well, I,ll "T" it into the hose going into the catch tank).

To be honest, I,ve never had ANY residue in the catch tank & thought this to be odd, no water/condensation or oil mist, but then again the engine hasn,t been run for long or in anger.

The catch tank does have a filter on the outlet point to fresh air .

cheers

i wouldnt worry about it. my pinto did the same thing and it had a full rebuild. its just condensation build up from running it up then letting it cool without going anywhere. as soon as you drive it the problem will go away.

andy stop thinking into things too much bite the bullet get it in for iva and fix the list of things it fails on. you will make yourself feel bad aiming for a first time pass. your better off spending the £90 on the retest just to relieve the pressure

yea as above andy - the oil in the sump/crankcase gives off vapours when warm / hot - it has to be vented. along with vapours from the top end [under the cam cover] usually to a oil catch tank in the kit car world. the OE way was to vent it back into the air intake tract to be reburnt. if its not getting vented it just sits on the oil and eventually goes white. also when fitting vent hoses make sure ALL hoses have only an up down fitment so gasses will rise up inside them. the tank should be at the highest point so any oil that does make it there can drain back down to the sump once the engine stops.. if poss..

get it finished man.. thats 2 stoneleighs youv missed..

are you going andy? if so we iz going down prob saturday night or sunday morning.. maybe the latter weather dependant

Good job its not on gas,it turns oil to milk and there is nothing you can do with it.

pull a top breather off any late 80's early 90's VW 1.8/2.0 and you will understand how blocked arteries restrict flow of blood. These gum up with horrid emulsifed oil..

andy as your engine warms up the hydrocarborns mix wit the oxygen in a diffrent ratio or ballance creating more h2o (water) that blows down the bores into the crankcase more ware, more blow by, more water in the crank case = more mayo
when a engine is used more it heats up nad the water is turned to vapor and expelled via the crankcase breather.
the problem is the crusty desposits that are created by the mayo gets into the oil pickup and colgs it over time.
this was typical of 80's engines that was over come with thinner oils of better quality and tighter running clearinces of more modern engines and fuel mixture control systems

hope that helps
