Evening everyone I've fitted 130 cams to 1.8 105 zetec and car won't start unless towed then runs rough only with revs has correct ECU 2FBC & throttle body. Timing seems fine im at a loss & wonder if anyone can help or point me into right direction king regards.

Are you sure there 130 silvertop cams ? and are there the correct want around as in inlet and exhaust not mixed up ? if everything is all correct there isnt any real reasion it wouldnt start if all was ok before fitting these... was it timed up correct ?

Kjlav

100% the correct cams mate they have the 2 identifcation rings on the inlet cam and were removed from an xr3i 130 everything off the conversion is off the same car. The cams are the rightway around as it has an Id tag that passes the cam sensor. Timing seemed fine we used pins and bar and even tried the old screwdriver trick for top dead center and still nothing mate It ran beautifully before it's a 40k engine.

You could try checkn crank sensor make sure its ok only other trouble ive had with zetecs is coil pack when there acted up... maybe check all the wiren plugs on harness just to make sure... The only other problem you will have is getting someone to plug it in as there obd1 so most plug in things dont work

Have you checked the cylinder compressions?
Have you checked / set the Cam to valve clearances?

BIG LEE

i was going to say to check compression then again if its bent valves its dead now anyways tho really if anything has touched

Kjlav

had plenty compression nothing catched when turned mate how do I go about setting clearances as I've put the original cams back in and it runs and drives?

Kjlav

swapped them over off other car have spark and fuel crank sensors two months old done all the tests but i cant plug it in as its a k reg pre obd bud

BIG LEE

Good stuff so its running now with old cams in? its a silvertop zetec there hydrolic lifters so you carnt touch tappet clearance etc its the blacktop zetec thats shimmed...

Kjlav

Running as normal mate with original cams it's an early zetec with Dohc on cover it does have the hydraulic lifters do you know if the 130 has different lifters or if the timings slightly different? Cheers.

BIG LEE

im sure there is no differnce in them ive got a set of 115 cams and full inlet manifold off a gti escort kickn around if you after an upgrade.. But im not sure why yours wouldnt run with them 130 cams in not unless there are not silvertop cams thats the only obv reasion tbh

Kjlav

The 130s have rounder lobes and two indentifying rings on inlet cam the 115 and 105 cams are identical sharper with 1 I'd ring I managed to get it running mate it was me not plugging in the throttle position sensor correctly 🤦‍♂️ 😂
