This is what me and my team are up to in the workshop today. 5.0 Range Rover in for head gaskets. Another mechanic elsewhere fitted a water pump and stuck everything with horrible black silicon. This silicon went round the engine, blocked everything and overheated the engine. I removed the engine, cleaned all the silicon out of it, skimmed the heads, levelled out the block and fitted new gaskets. Have the engine back in the vehicle now and hope to have it out of the workshop tomorrow night.

The only lubricant which comes in contact with crank shaft is oil either by touching (dipping) in early old engines or by oil drips from engine head as it was the only way to spray oil below pistons (lower part from combustion chamber) before using sprinklers (with check valves and pressure control valves) even dry sump have a metal cover below crank shaft with leveled drain holes to keep a minimal level to lubricate crank. when you mix vegetarian oil with air you can have a mayonnaise (and you still need to add an egg to the mix) but mineral oil and synthetic would not make that foam unless it have water, sugar or egg!!

A dry sump system keeps the engine oil in a separate remote tank rather than in a sump below the engine. It has a few advantages, Because you don't have a huge sump below the engine, you can fit the engine lower in the car which gives you a lower centre of gravity, improving handling. Sometimes when you go around a corner fast, the oil sloshes to one side of a standard sump, possibly uncovering the oil pickup pipe and causing oil starvation and possible engine damage. The crankshaft never gets dipped in oil which could have an effect on horsepower. Basically, because racecar. Perhaps some of the 4x4/offroad guys on the forum could give you better information on lift kits than I can.

I've done Hummer transfer box before. This one seems ok. Honestly, oil isn't my forte. I'm only really into the mechanical and electrical side of things but I have been told that the profi car stuff is good. We stock that alongside gulf oils. 9 times out of 10, people just ask for the cheapest oil possible and that is the gulf products. Most people driving cars don't have the same passion as we do on here, they just see a car as an appliance like a washing machine or a toaster and the main aim is to keep it running for as long as possible as cheaply as possible.
