Oil leaks on a CVH :(

[ZR1427]

I run a Sierra as a minicab and fitted a CVH 3months ago(20,000 miles),in that time the sump gaskets had a leak at the g'box end and ive tried fixing it but it now looks like ime gonna have to pull the motor and fit a new gasket aswell as fit new crank and cam seals as they are starting to leak aswell...GGGrrrrrrrrrr.

Question is what is the best sealer to use on the sump gasket and any tips to seat it without the bloody thing leaking,cheers.

It should be a 1 piece rubber gasket that is fitted to the oil pan without sealer.

Cam and crank front seals are a doddle,

*tip*
if the seals you are supplied with have a spring on the lip, when viewed from the rear side, the sealing lip should be coated with oil before you fit it.

if it's the PTFE type seal with no spring and a firm lip, it needs to be fitted DRY.

Thanks for the tips nighthawk.

No problems m8, feel free to yell if you get stuck m8.

Make sure you fit a NEW cam belt to if your going to replace the cam and crank seals.

Cambelt!! ,i had one of those go on a CVH a few years ago,i was only turning a corner at low speed and it absolutly b*gger*d some of the valves.

I might wait till it gets a bit warmer before i pull it,ile give you a yell if i get stuck.

The cam shaft drive belt on the 1.8 sierra's power unit is a doddle to replace.

Belt change on it's own should take about 25mins. There is loads of room to play when the engines IN the car, if it's out for repair it doesn't get any better

Some differences on the 1.8 from other CHV units fitted in the Escorts and fiestas as it's a North american designed engine.
