Re: Volvo Penta 2003 / Starting

Paul l, true, but it is normal to be able to re-seat the bottom of the copper inserts, either with the Volvo service tool, or with a suitably sized dowel fitted with a bit of sandpaper on the end. Use it like a hand valve grinding tool, and continue until the sealing surface is shiny and ridge free. Usually a good, leak free seal between the injector and the copper can be achieved, without head removal, and without replacing the copper inserts.
I have always been able to get them to re-seal, but I absolutely agree there are probably engines out there that need new copper inserts.
Leaks from the injector bases are pretty common on these engines, but, as above, not usually too hard to fix.

Matt
I took an injector to a machine shop and had them turn a blank to use as a finishing tool. In the end to get it leak free we had to replace the sleeves.

Mine looked like that, but turned out to be the return lines I think, just slightly loose connections which allowed fuel to build up in the recess around the injectors.

Re: Volvo Penta 2003 / Starting

Usually hard starting is one of three issues.
1. Low compression.
2. Loss of prime, means air gets into the system and makes one hard to start, I had an air leak in a filter bleed screw from its O ring once, engine was always hard to start, and sometime would shut down right after starting, requiring a restart. Eventually got so bad it wouldn't start and I had to find and fix it, it would leak air in when engine was off, but not enough to cause running issues once running.
3. starter not spinning it fast enough, sometimes this can even be wrong grade of engine oil. Low batteries, loose connections, worn starter.


Might want to google Diesel loss of prime, its pretty common

And No 4 would be because it is dammed cold.

VT, don't forget there is a decompression lever on the front of the rocker box on these engines if you want to spin it over quicker.

Re: Volvo Penta 2003 / Starting

OK, to test if loosing primed is the problem I can install manual prime pump like on a car and see if this fix the problem if yes will just need to change all houses with new one and new clamps and make sure I do not have leaks on the way

for the diesel around injectors will take a look at the return path also...
