How To Remove And Diagnose Engine Problems On A Porsche 911 Carrera 3.2L Part 1
Вставка
- Опубліковано 6 жов 2024
- My Carrera 3.2L Engine Has a Bad Misfire so it's time to drop the engine and diagnose what is wrong with it. Always do a PPI on a vehicle to know what you are buying. I'm a sucker for a good deal, so this car came home with me anyway. Now, it's my job to fix the engine and make it run as good as it looks. Wish me luck. Possible problems are a) broken head stud, b) bent valve, c) Worn out valve guide, or d) all the above?
Here's the cool hose removal tool: amzn.to/3RmSejv
Heat gun: amzn.to/4arbgOf

Time to remove my 911 engine. Thanks for watching!
Hey Tom, the heat gun and the special pliers did the trick to get the brake booster off my car. Thanks!
Always classy and professional sir.
You make it look easy, but I'm sure that took several hours for sure. Looking forward to part two.
Off and on for a few days
The car looks to be very original. Amazing job getting the engine out by yourself. Can’t wait to see what is wrong with it part two.
It's a nice car for sure. It needs a few things here and there but I'm looking forward to driving it more.
That reminds me of removing my 1967S engine to change the clutch. And I didn't have a lift. Nasty! But I'm sure you knew what you were in for because it's pretty obvious when the car is driving on five cylinders.
I've done it without a lift too, and I agree it's not as fun.
The driving symptoms are a very noticeable low speed misfire.
I happen to own a '77 turbo and a '87 G50, getting the engine drop is a bit easier with the G50, simply for the reason of shorter shifter rod which does not intrude into the cabin. Nice videos and very informative, thanks
!
Cool cars you have! I agree the trans disconnect is much more convenient in the 87
It's very little extra work to remove both drive shafts completely before dropping the engine so they don't get caught on the G'box. During one of my engine drops I snagged a shaft on something and bent up the UJ shield so that the bellows don't fit.
Also those little roller tube bearing in the clutch release fork are rubish and always wear out the shaft. I fitted bronze bushes in the fork and drilled the shaft so that I can pump grease in from the bolt side to lubricate everything. Great watching your engine drop, been there a few times.
Good idea. The G50 shafts don't separate from the stub axle like earlier cars, so it's a bit more work to remove and not trash the seals or bearings.
My trans already has the bronze bushings, but I guess they used the wrong grease? Or the shaft was already worn. Good idea to add a grease nipple.
You don't need to seperate them. Undo the big 36mm nut on the wheel side, a good tap on the centre of the spline shaft and they just pop out (in). All the seals and bearing stay in the hub, so much easier with them out of your face.
Bad man, great job
Well here we go again..... Something to do over the Hollidays. And while you're in there?
Lots of tidying up to do for sure.
g50 trans fits pre g50 cars with modification of bell housing, Patrick motorsport will do the mod as they did to mine and they also sell adapter for connecting it to the shifter than 930 clutch can be used which is much smaller than g50 one,
Good point. I guess the axles are at a slight angle then?
Great video as always, love the detailed explanation that helps us who are learning to better understand why you're doing the things you're doing. Also, we saw a 'fan fav' TomTool get made a used today, I always like that part. New tool day! Thanks Tom.
Thank you. I'm now engraving or tagging my Tomtools because there's so many that I can't remember what they all do.
I really like the level of detail in your videos, Tom. If you were dropping the engine/trans assembly working straight through without video recording, how long do you estimate it would take you get the assembly on the dollies?
And your seats look great. Also, the under carraige looks to be in top condition…no dents, scrapes, rust holes. Solid car.
Thanks Mike, it's a pretty nice car. The top needs some work, but the car is very original and complete.
I think I could remove the engine/trans in under 4 hours for sure, probably three.
I took Mac's engine out in about 45 minutes, but there is much less stuff to disconnect.
Nice looking 911. The 911 I’m building on my channel had 2 bad cylinders on a 8k mile motor. Turned out to be 2 bent valves and not the guilds that I thought.
Looking forward to see the next video.

Oof, must have missed a shift? I could have a bent valve too.
@@GarageTimeAutoResto mine was going to be a $150 fix for 2 valves. But went a head and had my heads checked and all looked great. But they CNC cut my 2 heads getting the new valves for the large sizes valves. So Zi got all new valves in all the heads for $1600 . And maybe a few extra Horsepower. It was fun learning to Porsche motors after a lifetime on old American hot rod work.
See you in the next episode.

Can you share who did the heads for you?
@@GarageTimeAutoResto Memphis Motor Works my motor is from Pat Williams Racing,also in Memphis. Pat worked at MMW before he stepped out of his own many years ago. Both are the top of the top in the Memphis area .
Cool, thx for the info. Hard to find good machinist for 911 heads.
The pressure is on!!! It’s a race to get my engine ready!!!
Yes, let's race 😀
Merry Christmas and Happy New Year Professor...
Thank you and same to you😀
You almost made it look easy! How do you like the MaxJax? Looks super useful without taking up a tonne of room. With cylinder 5 a goner, it's a "full" rebuild then?
The Max Jax makes it easy. I love it. Will most likely do a video replacing the seals as it just started leaking a bit.
I'll know more next week, but I suspect the heads will need a rebuild for sure. Pistons and cylinders are probably fine, so hopefully just a "top end" rebuild.
Hi Tom, great timing on this one, I'm just about to drop the engine on my 84 Targa. What is the tool you used to disconnect the brake booster line?
Hi Tod, Amazon link for hose pliers is in the video description. Totally worth the $10, but a heat gun or hot water helps too.
