PORSCHE 914 TYPE 4 ENGINE HOW TO ADJUST VALVES
Вставка
- Опубліковано 8 лют 2025
- We all need adjustment now and then. So do the valves on a Porsche 914-4 / VW Type IV! If your engine sounds like shaking a coffee can full of bolts and /or is losing power, you're probably overdue. Here's how I do it. It's not the only way, but it's simple and foolproof if you follow all steps. As a fool, I should know.
BTW, since I assume this video is for newbies, I decided to keep things simple and adjust the valves in firing sequence order. If you're feeling randy, after you're done with #1, you can rotate the engine backwards 180 degrees do #2 while you're still on the left side of the engine.
Here's also a link to Krusty's (rocking) method, which saves a few engine revolutions, but requires more attention. Honestly, I think this works best for people who feel compelled to abbreviate the month "June". ;)

Every 914 owner thanks you now 😉
....or curses me ;)
Just wanted to say that your production quality is fantastic! I love to see even the little things shot so nicely. Thank you!
Thanks for noticing! I can’t help myself…which is why these videos take a while to make :)
Ian, thanks very much for all of these videos! They're so well done and so well presented; priceless. Just bought a 75 914 1.8 project car and will be watching these over and over again.
Glad you like them! Please subscribe if you haven't already so you get notification when new episodes post...
Another good one Ian! Gonna miss you at Hayfields for the spring driving back east. Hope all is well out there. All the best from your engine mount borrowing friend, John.
Hey John! I’ll be at hayfields next weekend :). How’s your engine?
@@IanKarr Running strong! See you there!
You should probably mention that your valve adjusting lugs are not the stock ones. Yours have Allen heads, while the stock ones are slotted for a standard screwdriver. You've also got the solid spacers between the rocker arms instead of the stock springs. That doesn't directly affect the valve adjustment, but it does look different.
Since I have stock aluminum pushrods on my engine, all the valves should have clearance when the engine is at TDC. So an easy way to determine if a cylinder is on TDC is if its flywheel mark is lined up *and* both rocker arms have some slack on them. If you're keeping up with your adjustments, the clerarances will not close up completely so this is a good indicator.
The biggest pain in the butt about adjusting 914 valves is getting your hands and your tools into the right places for the adjustment. I can't even begin to imagine how you could show that, because you'd also need room for a camera...
You just did ;). Thanks Dave!
I like your Allen head adjusters instead of having to use a right angle screwdriver. You should be using the angled feeler gauges instead of straight ones. Use your thumb and forefinger to hold the individual feeler gauge so you can feel a slight drag when adjusted.
Thanks for the note. Angled feelers are def the way to go when the engine is in the car....
Thanks Ian! Hopefully I’ll be performing this job in early summer!
You can do it!
The valves are hard to get to with the exhaust on the car. I did the push rod tube seals/o rings a while back with engine in car. I took the exhaust off for that job and spun the wheel to get TDC. Thanks for the video.
Not really hard to get to...but hard to see. Small mirrors help ;)
Great video sir! Thank you for doing this!
Glad you found it helpful!
You should let people know to do this with the engine cold. Let it sit for an hour after running it and then adjust your valves.
You just did :) thanks!
I had the 73 2.0…I found 6 and 8 feeler gauges with a 45 degree bend on the end…made this easier.
great tip!
Hi Ian, hope all is well with you. I want to ask you about your black 914, what happened to him?
I want to take this opportunity to thank you for the videos you make in honor of 914, they have been very useful to me, thank you very much!
Thanks for saying hi. The black car is doing well! It's currently at PMB Performance getting the final touches. More episodes to come on that.
Oi Ian, espero que tudo esteja bem com você. Quero te perguntar sobre o seu 914 preto, o que aconteceu com ele?
Quero aproveitar esta oportunidade para agradecer os vídeos que você faz em homenagem ao 914, eles têm sido muito úteis para mim, muito obrigado!
Obrigado por dizer oi. O carro preto está indo bem! Atualmente está na PMB Performance dando os retoques finais. Mais episódios para vir sobre isso.
Do you have to remove the engine to adjust the valves? Because there is no room zero room to do it in car
You definitely don’t need to drop the engine to adjust valves. It’s tight in there, yes, but there’s enough room to get your hands and tools in.
Well, that's all good and well. How do you adjust the valves with the engine in the car
The same way. Just from a little more below. You can do it!
nice! I like the new garage.
Thanks! I do too ;)
Excellent vid
Thanks!
😊
