Thanks for posting. Your video really helped simplify the procedure.
Thanks for posting Ranger Fortin. I just bought a 56 plate ranger and the first job is to check the valve clearances.
Thanks pal this will come in handy for my 2006 Ranger.
I wish I had watched this before I did mine. It is quicker than using the method in the workshop manual. I parked my (manual gearbox) truck on a slope. Took note of which lobes were pointing up and set those valves. Rolled the truck forward and continued the process recording which rockers I had set.
No need to remember if you lose all the regulators before start adjusting
Thanks mate ... great video ... huge help
Thanks mate, fantastic video with clear and precise info.
good video....watching from indonesia...🙏👍👍
Good vid explaining sorry you didn't put the camera to show what you was doing properly, but God explanation
Gday Mate. Thanks for a great video. Dunno if you can help me but ive got a Mazda B2500 (same engine) that keeps tightening the valve clearance for some reason. Do you know of any issues with these or have you had similar problems and found an answer? Thanks for your help.

That can happen.
Apply a dab of lower strength loctite to nut
what are the benefits of doing this to your engine ?
Thanks Ranger Fortin. But how do a rocker arm damage?because my mazda b2500 after the engine tune up of the valve clearnce the rocker arm are broken and the valve guide is go out into the head.
Hi Roland, I was just passing by today and saw your post.
It looks like whoever did the valve clearance did it on the wrong position with the camshaft lobe pushing the valve head into the cylinder (this engines are called interference engines, which means if the timing belt jump teeth or get broken, the pistons will start smashing against the valves) and with the extra clearance given when adjusting 0.1mm, will be enough for the piston to start smashing against the valve, that's the reason why the rocker arm broke and the valve steam went into the cylinder (very probably the broken rocker arm continued working but not pushing the valve at the end of the stem but just pushing down the spring plate which made the the valve collet to become lose and and falling down allowing the valve to be dropped inside the cylinder.
There are two ways to make the valve clearance adjustment, one is the way shown on this video and the other is by adjusting all the valves which the camshaft lobe is not pushing them while No1 cylinder is in compression, then you do:
No1 Intake 0.1mm and Exhaut 0.2mm
No2 Intake 0.1 mm And Exhaust (Do not do it)
No3 Intake (Do not Do it) And Exhaust 0.2mm
No4 Intake (Do not do it) And Exhaust (Do not do it)
Now put cylinder No4 in compression, turn the crankshaft a full turn or half a turn of the camshaft or when you see the 3 camshaft lobes on number 4 pointing up, they wont be all at the uppermost point at the same time (due to synchronization and valves overlap, they will form a sort of V and you must set the V straight up like "V", then you star doing:
No1 Intake (Do not do it) And Exhaust (Do not do it, already done)
No2 Intake (Do not do it, already done) And Exhaust 0.2 mm
No3 Intake 0.1 mm And Exhaust (Do not do it, already done)
No4 Intake 0.1mm and Exhaut 0.2mm.
Normally I lose all the regulators before starting to adjust them and tighten them up when they get done, double check when you finish that all regulators have been tighten.
Hope this will help.
@@reneahumada8520 Thanks for this guide mate. It helped me a lot doing the valve clearances on my 2002 Ford Courier 2wd.
What year car is he working on here ?
Really great video of your shoulder and not the engine you’re working on..
Keep spirit.......
WL engine thickness gauge, tell me
In...? And ex...?
How come the cylinders of the valves you adjusted weren't put into a "compression" TDC?or at least I didn't see you do it , i keep reading multiple write ups where it is apparently important that the cylinders of valves be at a compression tdc... any advice to clear and straighten up this misunderstanding would be appreciated 👍
Not important on engines like these, it's just people being pedantic. However, you must use TDC when timing the camshaft or things will go south really fast
Use the rule of 9 or put them to tdc on pushrod motors where you can’t see the cam
On these you can point the cam lobes upright then yiu know your on the base circle and can adjust the clearances
Hi what year mazda bravo turbo diesel 2.5lt are you working on here please ? I have a 2004 bravo 2.5lt turbo diesel wlt will this be suitable for my engine? Good video ,cheers
Take care when breaking lock nuts loose especially with socket and ratchet, break them loose with cam putting pressure against valve spring to avoid snapping rocker arms, known fault. Then turn over to point up to set. Happened to me last time, to replace cam has to be removed.
If you do snap one you can wind the adjuster all the way out and thread it under the cam 👍🏻
Does anyone know where the IAC valve is for these engines? I can't find any info anywhere.
You won’t find it because it’s a diesel
@@rangerfortin1504 Oh, makes sense. Thanks for responding. It's my first diesel and I get a slight rough idle when cold starting, for about 5-10 seconds. I guess I should look at those glow plugs.
@@techatsepale2819 hey bro can adjust the cold start to a higher rpm and that should sort it out

Can I know what it mean cold?
It mean engine cold or weather cold?

My engine need help
Benefits of stock sized tires, you can reach the rear two cylinders from the front 😅
