hi all there`s no heating in the car ... motor blows air but it`s not hot ... any ideas why ? heating matrix bypass mod ? :)

I bought a sump plug a while ago from Z1 and fitted it yesterday whilst doing and engine flush. When I dropped the second lot of oil I saw some debris on the magnet. I thought - that's cool it's obviously doing it's job. But NO! The magnet on the end of the sump plug had fowled a baffle plate inside (I assume) and half of it had disintegrated and the debris was the broken bits of the magnet its self. I'm not sure if i have all of the magnet pieces but I hope so. If not, then that means there are bits of magnet debris somewhere in my block! When I compared the length of the two sump plugs, the magnet was about 4mm longer than standard - just enough to cause …

How is an Engine Oil Made? There are two main components that all engine oils are made of, basestocks and the additive package. The base fluid typically makes up the bulk of the oil (70-95%). Additive chemicals are then added to enhance the positive qualities of the basestocks and to overcome whatever negative qualities there may be. There are two main types of basestocks, petroleum and synthetic. Petroleum basestocks are a purified form of crude oil and have been used as the base for automotive lubricants since motor oils were first developed. Synthetic basestocks, on the other hand, are chemically engineered in a lab specifically for the purpose of l…

Hi guys i have been reading though some of the old post regarding head gaskets and i see that you both say that its better to replace the engine or do a major strip down rather than do the gaskets if its been over heating. Now im looking to take my engine out for other work and i was thinking of doing the headgaskets while its out. I have no over heating problems at the moment and have not had any since i have had the car and as far as i know its not been done before. My question is am i better to leave alone or will it be ok to do with out having to strip the engine down any further than the head gaskets? Thanks dave

Need a bit of help here, When the car is not running i can slide throught he gears very easily. When the car is running it is quite stiff to get the gears home. I am running a Z1 shortshifter but am wondering why it is harder to change gears when the car is running? Is there something mechanical i should be checking as well as the fitting of the short shifter? Cheers

Ive recently replaced front discs with ebc drilled and grooved. And red stuff pads. After maybe 2 months driving ive developed a vibration at about 40mph under braking. I changed the discs and pads for brand new standard pads and discs and the problem seemed to go away. Until the other day when the vibration returned. They were only on the car for 2-3 weeks. Could this be the hub or is there something else causing the problem? Its doing ma head in and also costing me!!
