Engine Oil Viscosity Viscosity is the most misunderstood aspect of oil and yet it is the most important. Viscosity is the force required to shear (break) the oil at a certain speed and temperature. Oils work because they have viscosity; the drag of a rotating part pulls oil from a low-pressure area into a high pressure area and “floats” the surfaces apart. This is called “hydrodynamic lubrication” and crankbearings depend on it. Oil must be capable of flowing at low temperatures, so that it gets around the engine in a fraction of a second at start-up and must protect engine components at high temperatures without evaporating or carbonising and maintain adeq…

I'm considering having a Toad alarm system fitted in my Zed. Does anyone know of any issues with it working alongside their turbo timer?

Hi Can anyone tell me what order the cylinders go in if im standing in front of my car? Cheers

Sio any comments gratefully recieved or point me in direction of a good insurance thread

I can't remember ever seeing this in the list of things to check for poor running or idle.. the IGN COIL replay in the engine bay main fuse/relay box. the pins can become rusted or loose, certainly worth a check (obviously it supplies power to the coils). I saw this on another forum just the other day, the guy posted it because it was the cause of his bad running / hesitation .... checked cleaned, reseated and problem gone.. :)

I am currently putting back the instrument cluster and there are 2 wires that come up and attach to the back of the panel, on my car it has a kph/mph converter box. Question is , where do these 2 wires screw on to. i remember they go onto already existing screw heads, but which ones, HELP!! Rich

Has anyone here replaced a worn strut top? I have what I think is a worn near side one. The main shock nut appears not to be in dead-centre like it does on the offside, in addition I get a very faint squelching sound from that area at low speed over speed humps. Just wondering if anyone else has had this problem before? I've had it on a car I owned years ago and the symptoms are similar.

tonight i started preparing my new bumper to replace the current one which needs the top of it repairing(not a major job). Mikey bean was gonna bin this so i saved it from its fate and got it all painted up tonight. still needs buffing smooth and im probably gonna lacquer it too to help protect from stone chips. hopefully get it fixed on my next day off.

Hi all, Im debating about what to do with my bumper. Do I keep the Abflug type 4R and have it repaired or go for a different style like the wings west bumper or terminator. Has anyone got any pics of the wings west or terminator fitted with a FMIC? Cheers Dan

Well today I went to fit the hard pipes for the oil cooler and realised the hoses that go from the oil tree and the return one to the sump have been cut...... Obviously the person who supplied the engine decided to cut the ends off the hoses rather than undo the clamps.... Has anyone got some tips for replacing them? I can't get to the oil tree one as the steering rack and engine mount are in the way..... Also, which pipe has the restrictor in it? Is it the 2 pipes from the engine to the hard lines or the 2 pipes from the hard lines to the oil cooler? Can I fit braided hoses instead and lose the standard lines with the restrictor or do I need to use the old…

Hi everyone. I have what I believe is a split Turbo Oil Hose on the Drivers side. It's the one next to the water pipe. I have uploaded some pictures in the hope that someone can confirm what this hose actually is tho i.e.Turbo Oil Feed Hose, Oil Return feed hose... When the engine is switch off after a drive you can see little puffs of oily smoke coming from the bottom of this hose onto the hot turbo. Also if someone would be kind enough to tell me if I can get a replacement in Silicone, braded or even original that would be great! Don't know if Mike at MJP would do these... Thanks in advance people...

Hi all So I've got my dream 300XZ but the list of problems is quite long The main fault I'm trying to diagnose and fix is missfire on cylindersl 1 and 2, two front cylinders as you look in engine bay.Fault is permanent cylinders don't fire at all. I've spent few hours today and got to dead end,basically I've swapped ignition coils from other working cylinders and spark plugs - still no good,checked voltages on 2 faulty coils and there is +12v,earth,and continuous +12v on trigger pin of both ignition coils.Compared with other working coils and 12v on trigger pin should colapse for spark to take place. OK checked continuity between coils and PTU all ok,checked tr…

Looked like it had flat wheels similar to the Porsche 959. 2+2 and I think (from the distance) a TT. Saw you pulling out of the petrol station around noon time.

Yep you guessed it. Time for the MOT :thumbdown:

http://www.countrymanvehicles.co.uk/rac_silver.pdf Am I missing something? Seems they will put a warrenty to any car of any age with any mileage costing over £1500. I'm going to try and find a price for the zed

Just noticed a listing on Ebay for a UK spec Cruise Control Module - £20 plus delivery. They claim that fitting this UK module to a JDM car will allow cruise control to be set at speeds above 69mph. Does anyone know:- 1. Will this allow higher CC speed settings? 2. Where is the CC Module located? 3. Any gotchas? Many thanks

Q. Why did the man drive his Zed 135 miles a service? A. To drive the 135 miles back. :tongue: Cheers Jeff.
