SOURCE: Mazda pick up B 2900 valves clearance

THIS IS FOR A B3000 SERIES.
The manufacturer indicates that this vehicle has hydraulic lifters or adjusters and therefore does not require adjustment.
THIS IS FOR THE B2300 SERIES.
Midrange clearance is the most desirable:
Intake 0.22 - 0.28 mm (0.008 - 0.011 inch) Exhaust 0.27 - 0.33 mm (0.010 - 0.013 inch)

SOURCE: B 2500 diesel pickup hard start from cold

Hey mate,

I have a Mazda B2200 from 1985, which has the same R2 diesel motor, and I had this same problem, which was exacerbated by the cold of winter....even here in a mild Melbourne.

Each time you turn the ignition on, the QSS (Quick Start System) powers up the glow plugs for about three seconds. This recycles again about three times, then.....nothing. The QSS reckons that you ought to have the bugger running by now!

In my desperation, I located the cable to the four glow plugs, and ran a second wire from the battery (+) via a push-button switch which I installed on the dash. This is my glow-plug BOOST circuit.

Now, when I want to start from c-c-c-cold, I push the button (with the ignition on) for about ten or fifteen seconds, which gives the glow plugs a goodly time to heat up the combustion chamber, and when I hit the starter, she usually fires up with a rattle, and a cloud of grey exhaust smoke.

BINGO!

(Of course, once the motor has warmed up, there is no need to use this BOOST circuit, for the combustion chambers are already hot enough to detonate the injected fuel.)

Have a go at it, as I know that it works!

John.

SOURCE: noisy startup when cold, sounds like valve

Hello onarock844...The Hyundai 2.4 litre and the 3.3 litre are known to have valve train noise. Some sooner than others.
The timing chain tensioners on the 06 and 07 Sonata 3.3 engines built before August 4, 2006 are well known for developing wear that allows them to make a tapping or rattling noise for a short time after a cold start. This noise can be mistaken for a lifter noise, although the actual source is in the front cover area of the engine. Hyundai has released a technical service bulletin on this problem, which describes installation of an updated design timing chain tensioner (part #24410-3C300) to correct this noise issue.
Ask your dealer to refer to Hyundai service bulletin #06-20-002 for information...If this has already been corrected,,,and the noise is coming from the upper engine area and not from the timing chain area, then the valve clearance will need to be adjusted. This is done by disassembling the valve train and installing slightly different size tappets to change clearance.
This is a fairly labor intensive process, so if you are still under factory warranty then you will want to go over the dealer's head and get the Hyundai zone rep involved to get it covered before your warranty coverage expires...
I recommend useing a full synthetic engine oil, i know in a few cases where the noise has stopped when the oil was changed over to synthenic, also a high quality filter is important, such as a purolator.
Good luck...i hope this helps...please rate me a fixya.

Hi Ace 2L diesel van. What is the valve clearance warm and cold?

The 2L Toyota engine runs an overhead cam with bucket lifters, and requires removing and replacing of shims to adjust clearances...

I have a Hatz1B20 diesel engine and it starts easily cold but will not start when hot?


check the tappet clearance when hot should be .012" inlet and
.14" exhaust
if the engine has a lot of hours on it , it may need a pump rebuild or the injectors rebuilt but I suspect a valve problem from the tappet clearance being to tight cold
