Verniers will allow maximum air to be in the cylinder during compression yes, cos the valves will be working at the exact right time not just within a tooth of the right time

TDC does happen every 360deg of crank roation, but you need TDC and the cams set to the same place. You don't set the engine from tdc as vx didn't set the marks to be at tdc, it's just before, but the cam timing marks are set aswell, so although it's out it's right. Very odd, but that's what they did, so dropping a long screwdriver down isn't a great deal of use, unless you're runngin verniers and setting the timing spot on.

To set the tension, turn the crank so the slack it taken up on the exhaust then the inlet cam, without moving the water pump (rotating if you will) this will move all the slack in the belt to the tensioner then with your other pair of hands set the tension. then rotate it. and check it again.

Also when you put the belt on, set the crank to TDC, then put on the exaust cam and slip on th einlet cam, you may need to roate the crank slightly to get the slack where you want, but it's always a tight fit.
And claret is normally spilt, cause of the damn exhaust pulley sticking outty feckign sharp bits.

You can't just bang it on and tension it. It needs rotating and then tensioning. as the slack between the pulleys will move round as soon as the engine run. It's because the cams like to rest as close to the lowest lift as they can, which means they aren't sitting in the excat place you want them to.reverse th einlet cam a fraction so it's tight bwteen them, and set the tension. then roate the engine and check timing and tension, normally take a few rotations till it's right.

At least ya didnt get ya timing 180 degrees out like i did, lol, dont do no damage just sucks when it should be blowing lol

just turn the crank with spanner loads of times.... if it was lines up after that..... then switch it on... there really not that hard to change

although i was expecting crunching noises when i did mine:o:lol:

i'd rather make sure the belts good before i turn the damned key thats all :lol:

its a new belt i put on... pain to fit really

when i bought my engine it had been left lying for 5-6 months... when i went to do the timing belt the inlet cam looked like it was a tooth out... the to cams werent in line cos the cams had settled.... hard to explain....

i ment turn the crank with a spanner not with the starter....

Check the routing of the belt and i wouldnt rotate the engine till i knew it was timed right, if its near TDC drop summit in No1 cylinder like a welding rod to check the piston is at the top, when i did my belt i didnt have any slack

it will go slack if the engine is left for a while.....

rotate the crank about 8-10 times and if all the marks line up its fine....

Should the bit between the two pulleys at the top have much slack in it... coz mine looks a little too sloppy.. need to know before it goes in this weekend really, the tensioner indicates correct tension, but it looks a little slack :thumbs:

Cheers
