How to reset the gap between valve stems and rocker arm on a D4F702 (1.2A 16V) engine froma Renault

The vehicle used for this tutorial was a Renault Twingo MK1, but it applies for a lot of Renault / Dacia models.

Great and helpful tutorial. Please beware that many D4F engines have two different camshafts; with and without a groove. The gap values are different.

How to find out which camshaft I have

[@jrvd64]

@@wario4979
There could be a groove visible between intake cilinder 2 and outlet cilinder 2. You have to use a light and look very carefully.
Camshaft without groove.
exhaust valve clearance between 0.20 and 0.27 mm.
inlet valve clearance between 0.10 and 0.17 mm.
Camshaft with groove.
This camshaft is identified by a groove between the cams (A2) and (E2). Repeat the adjustment procedure
for the valves indicated above, with the following adjustment
values:
- inlet valve clearance: 0.25 to 0.32 mm,
- exhaust valve clearance: 0.35 to 0.42 mm.

@@jrvd64 will these spec apply for d4f 722 engine? keeping in mind of the camshaft groove

[@jrvd64]

@@costinc.6525 sorry I do not know. You just have to check the camshaft as described above.

Brillant tutorial! Thank you!

Great video!! It encourages one even to do it himself. Thanks!!

Hi, thanks for the video, i was unable to find a mechanic so far who would set this up for me, now i can do it myself. That's basicly a lifesaver :D

[@MrMariovfr]

Thanks again. Only two spark plugs were wet. There is no oil consumption so I think it could be most likely a sealing problem. But the compression check is a good advice.

[@businesswolle666official]

good and informative video! Good job!

[@Planefix1]

Excellent video 👍

[@marekmarkowski8683]

Great video, Olivier... thanks for posting!
I love how you show the blinking highlighted elements - so professional!
How did you do that?
Question for you:
Why is the adjustment done this complicated sequence and the usual way with the cylinder at TDC with all valves fully closed so both the intake and exhaust valves can be adjusted one cylinder at a time? Seems much simpler... Or is this a Renault special? ;-)

What is the torque specification for tightening nut?

[@MrMariovfr]

one of the best tutorial ever... thanks!
I found oil in the spark plugs tubes. Can you tell me how I can fix it?

[@olipirard]

Hello MrMariovfr,
Before fixing the issue, you have to know where this oil comes from.
Do you have oil in each spark plug well or one specifically?
Does the oil come from the top or does it come from the spark side (very dark sparkplugs)?
If it comes from the top : 1) the seals surrounding the spark plugs well might be cooked and so the oil finds a way to go out of the engine.
2) the sparkplug well might also be loose.
If it comes from the spark side, this is not good, because it means that the piston rings are worn.
To nail it, you have to perfom a compression test.
You have tons of videos on UA-cam about the topic.
I hope I helped you.

Thanks for the video, I'm busy trying to get this right with a logan with k7m engine, would it apply here?

[@olipirard]

Hello Josh,
Sorry to answer so late.
The procedure is the same for K7M engines.
The intake valves gaps = 0.1mm
The exhaust valves gaps = 0.25mm
I hope it helps.

Modus 2011 D4F-Turbo valve position ? Thank you

[@ciprianvirjan]

Thank you, but after how many km is required such an adjustment?

[@boroz0r]

I read on Internet after 100.000km or if your engine is noisy

[@chnmci4866]

moteur 1.2 16v pcv valve location ?

[@mohaarhly2950]

Monsieur Pirard, what do you mean with low Position?
Full open "down" or full clos "up or high" ?

[@olipirard]

Hello,
Thank you for your remarks and forgive my poor English.
By "low position ", I meant "down"

0.05mm admission and 0.15mm exhaust at cold engine(20C)?

[@olipirard]

Yes, at cold engine.
Ambient temperature.

[@torentmonkey]

Did this and idle is now very VERY unstable. Did it once 0.10mm on intake and 0.15 exhaust then went 0.10 intake and 0.20 exhaust. Problem still here. Changed gaskets , o2 sensor, cleaned thorttle, spark plugs look mint, smoke tested the intake manifold. Idle goes very very rich and car starts to sputter. Driving is fine. IDK wtf happend to it :(

[@decision4475]

Cylinder numbers should be numbered from left to right. So, from timing belt side to the transmission side. 1 - 2 - 3 - 4

[@r6bluestar]

In Renault engines are from 4 to 1 ( 1 is the first from gear box side)
