Thread: My first post and my s3 diesel ute

JDNSW how long would it take to crank it over and start it on a normal summers day if you hadnt started it in a while???

mine takes a bit of cranking with foot to the floor before she fires up.

Foot to the floor while cranking is the correct way to start 2.25Ds (and other IDI diesels).

On a hot summers day mine will start with just a few seconds of cranking (no glow plugs).

In winter - 30-60 seconds of glowing is needed. I (like others) have found that cranking for a few seconds to put some fuel in the chambers, then glowing, speeds the process up slightly.

ok well mine takes prob 30- 60 secs of cranking in summer to get going so i guess she needs a tune and is the reason for alot of bluish white smoke that it blows as well. but once its going it sounds a runs great. apart from the smoke when there are some revs under it,

Great thread Muckinhell et al. I am learning heaps about my 2.25D also.

hows your truck for starting and how does it get vacuum for the brakes sleepy?

She starts fine - 10 sec of glow plug first thing in the morning, a couple of cranks and away I rattle. Blows a bit of white smoke until warm. Motor was rebuilt only 2 years ago so runs and starts great.

As for the vacuum I understand there is a butterfly arrangement on the inlet (Ben or John can you please explain again for me too)
Here's a pic of mine...



I recall Ben saying you can get more power by removing it and going for an independent vacuum source, which I will get to eventually.

Blue smoke is oil - sounds like your valve stem seals or rings need doing. Which likely means you are down on compression - hence the slow starting.

The 2nd pic - directly down from the fuel filter, shows the butterfly - and the vacuum line off the top of the intake. The butterfly is a huge restriction in the intake, which diesels shouldn't have.

if its rings whats the cost expected to renew those or would a whole rebuild be more benificial....

mine doesnt have that butterfly anymore so im looking as you will have read previously in here into an alternate source of vacuum preferably a alternator with vacuum pump but not a new one as there upwards of $400 and 12v vacuum systems are that price too approx. So im also looking into other diesel vehicles vacuum systems to see if i can adapr one of them somehow.

by the way nice s3 wagon i read the thread about that truck...very nice.
