237 MG Tech | Oil Pressure Relief Valve on MGA/MGB

[@THOMMGB]

A good video, John. I have replaced this oil pressure relief valve from the top of the car rather than from the bottom. The trick I learned is using my LEFT hand to do the turning, not my right hand. My right hand wouldn't work in the correct way to turn the cap. Using my left hand to turn the cap worked perfectly. For what that's worth... Tom

I find having an arm with 4 elbows to be very handy for engine work....Great idea, John. Love your videos...Five years on, and it's still speaking to us! You guys are the tops!

I love tips like this from the Voice of Experience. Thanks, John!

After all the worry of low oil pressure during idle especially I tried this and it is now perfect. I did this with the motor in the car using a socket and a crow bar to keep pressure on the spring while turning, it worked! Sure do appreciate this video. Thanks so much John. By the way, Thanks for your service!

Wow, now you taking the video shooting seriously, I love all your videos. even that I don't own those cars but still similar to the one I have. THANKS John and the camera guy you're cool too.

Jhony Lopez yes I have rebuilt the engine 1800 CC and I'd like to know how I can make sure the oil pump is working is there something I can go inside the motor and turn something to make sure the pump is working for a started

I’m having a very tough time re-installing the oil pressure relief valve for the same reason…not enough wrist strength. Engine is a Cummins 6CTA-8.3 on a Nordic Tug. My troubleshooting manual suggested inspecting/cleaning it when my oil pressure fluctuates from normal all the way to 150psi. I did clean it but am now stuck at anchor until I can line up the threads. Wish me luck!

[@randyWCG]

Leverage saved the day! I keep a 24” nail puller/crowbar in my toolkit. I found a small ledge and used the bar to lift and position the threaded cap. It took about 20 tries with shaky hands but, I finally succeeded. The tip to precheck the alignment of the cap was very valuable!!

[@wallisparnell4464]

Notice while going through my motor that some dealers catalogs, show a little packing in the relief cup? Anyone know if this is important and which engines need it?

[@PREYNikolay]

hi. is it possible to clean or fix the valve control and relief valve cause dealer does not selling these parts separately? what i can do? thx.

[@rorto002]

Quick question; What is the size of the bolt?

[@jsc0338]

Will this cause oil pressure to increase when accelerating ?

[@toddbjerknes3563]

Nice video. My problem is that the piston is stuck in the engine block, any idea on how to get it out?

[@tttman1234]

didn't john say to bump the starter and oil pressure should push it out?

[@wallisparnell4464]

Got mine out with wooden dowel that I gently tapped into the cup hole and it pulled out.

[@Clayton.J.Bryant]

DO NOT TRY THIS IN THE CAR, I did and worked around 8 hours to get it in again. After all that, the oil pressure is the same as before. To make it more fun, the car slipped off my floor jack into my radiator, $280. The good news, I will have a new radiator.
