When I ordered the valves the exhaust stems where longer then the stoke ones. Is this wrong or is this some kind of after market thing. I don't want to start if they will mess up my car. If the exhaust stems are bigger what does it mean?

(I know I put 1990, but it IS a 1985. It would not let me go past 1990.) When the car is cold, it has some issues turning on for some reason. I don't know what it could be, I'm no car specialist. It's not the battery because that was already replaced. Any ideas?

I have replaced all temp pickups and fan switch, thermostat (drilled 3mm holes X2), have replaced the reservoir tank.
While thermostat cap was off, checked impeller, used torch and screwdriver to c if impeller is broken or loose (100%). NOT loosing water, no oil in water, no vapor out of exhaust.
Put a manual over-ride switch on fan, temp keeps climbing. Took head off, checked (NOT blown gasket or cracked). Took all hoses off and forward and backward flushed everything, yes, heater on full heat. Took radiator out and flushed as well and inspected (100%). The system gets presurised, can feel it on the hoses can c in reservoir as well the water squirting. Asked a mechanic for advise, he checked everything as well, and said, "Hey pal, you have one hell of a problem. All my ideas are done."
Please help, I've now spent what funds I had and still no solution.

my brake pedal goes to floor, but will pump up after several hits on pedal. have bled brakes, checked wheel cyl for leaks. Also idles perfectly until I try to accelerate from stop. once moving fine. Am thinking vacuum somewhere?

The starter won't turn on. There is a full battery charge. The starter has 250,000 miles and 22 years of use. How much should we expect to pay to have it replaced?

It is actually a 1985 Jetta with a 1.6 turbo diesel
