General marea 2000 timing marks

[wolfe01]

I have a marea 115 elx 1.8 16v and the cam belt went at the weekend. Thankfully a friend is a mechanic and has done the repair work but need the timing marks to finish the job. Don't seem to be able to find them anywhere, if anybody has photos or the timing diagram including all pulleys I would be eternally grateful.

Fiat use locking tools , my Haynes gives part numbers 1860875000 for the camshafts and 1860898000 for the flywheel ( although you could just find TDC on no 1 then jam the ring gear. ) There should be a locating peg between 2 of the crankshaft pulley bolts, when you have it right it should be at its closest to the bottom of the crankcase and point to the indent in the end of the sump cover. Thev pulley is keyed to the crankshaft
The cams locked are no 2 at the back and 3 at the front. worth changing the water pump and the idler while you have it in pieces. I'm not sure you can do it without the tools , but hope to be proved wrong.

:bang: Hi, my adjuster went three months ago the garage that changed my timing belt should have changed it. All 16 valves went!

I got hold of a second hand head and put it on, the trouble I found with the camshaft locking tools was that the stock bolts that are used in the camshaft bearings that you use with the locking tools dont seem to have enough thread on them to keep them in place. "They kept moving slightly"

I have put every thing back as per the manual, the engine turns over but will not start. I have a feeling that because I kept having to secure and keep the locking tools in situe the timing might not be spot on!

The last time this came up it was 5 pot car (I think, you can do a search) after a lot of work it turned out the Fiat cam locks were wrong!:bang:
Of course you should check the crank position sensor and all that stuff. Being one or two degrees off will not stop the engine running. In fact a vernier cam will often give as much power increase as a gas flowed head, and we used to retard single pot motorcycles for trials so they would pull stumps at 100 RPM, no go at the top of course and you could light a fag off the exhaust pipe
Now with a 4 pot car firing 1342(which the Marea is ) you can apply the rule of 9 to the valves (counting inlets on cyl 1 as 1 up to exhaust on 4 as 8, so ignore the fact its a 16v engine). So when the valves are set correct you have no 1 on the back of its cam and no 8 fuly open ditto 7 and 2 5 an 4 etc. So a quick check would be find TDC on cyl 1 with 1 and 2 valves (its in and exhaust, fully closed then 8 and 7 should both be open, ie that cylinder is in the overlap phase of its vavle timeing. The only other possible would be that it should be set to the other part of the cycle and its no 1 on overlap and nop 4 on compression. Have a look, turn the engine by hand to ensire no interference as well.
