'91 1.8 Driver.. Again

[Billy213]

Okay so my Driver still isn't going. Exactly the same as before. Fine under idle, runs like complete sh!t under load (Jumping/spluttering/failing in general until it stalls). I've changed and checked so much now and still nothing. Starting again for some fresh ideas and hopefully an answer..

What I've done;

• Spark plugs
• HT leads
• Dizzy cap + rotor
• Fuel pump + filter
• Earths cleaned/reterminted
• Air filter cleaned
• Starter motor
• Carb cleaned + adjusted + serviced
• Inlet manifold rubber gasket
• Looked for arching/sparking in the dark
• Runs like sh!t in all temperatures/humidities etc. so unlikely to be icing
• Timing

Anyone?

Do a compression test.

Check the timing's not 180degrees out.

[Billy213]

Timing checked with a light and seems to be fine. I've got no idea how to do a compression test if I'm honest. Definitely something I'd have to pay to have done.

[Diamond Hell]

Buy a compression tester for £15 online, or £25 from Halfords. 

Remove a sparkplug and wind it in, then turn the engine over with the king lead removed.  Test all four cylinders and let us know the results.  They should be within 10psi of each other and should be around 140-160psi or thereabouts.

Will this do?

Edit: Ordered. I'll let you know how I get on.

Okay thanks. Probably wont get this till at least Thursday next week at the earliest. I'll have to come back and let you know.

If anyone else has any ideas I'd love to hear 'em. Getting seriously fed up with this now.

I can take it into work and prove its accuracy if necessary. What's worse case scenario if one or more cylinders show bad compression? I really can't be doing without a car for any longer with new work commitments.

[Diamond Hell]

Medium case is head gasket has gone, so head off, skim and back on with a new gasket and bolts.

Worst case is you find it's gone before and the head's already had a skim or two and is junk.
