Rookie 3.0 rebuild

[Amstaff]

I did a lot of research and opted to go with ARP rod bolts. Spent some time on the phone with the guys at JB Racing in Tavares Florida and decided to have them recondition my rods. They were packaged up today and shipped to them. Looking forward to my follow up call once they inspect them. Look for pix when they come back.

Good idea is to get the cooler cleaned done by someone with an ultrasonic cleaner,reason I asked is that your motor is very low mileage and most likely has suffered for that reason,slow runs to the shops to buy the a ice cream,etc or just limited warm -ups due to short runs,your cooler will most likely have oil vanish on the inside of the tubes best to get that out for a modest cost.
People call these air cooled motors but the real cooling is done by oil cooler,thats the key point.
Good luck with your build .

Good point porsche tub. I will have to hunt down someone in my area to do it.

Here's where sent mine, if you wanted to use them the work you get back will be worth whatever it is that you spend plus your shipping. Full tank submerge, pressure test and cleaning. Here's what you get back.

Good luck in whatever you decide

[Amstaff]

Thanks for the advise Mike. Since you had a good experience with them I think I will send mine that way. Can you tell me what the cost was?

[Amstaff]

Today I mated the pistons and cylinders. My ring compressor worked great. Note that it has bands at the bottom which should be positioned where the piston goes into the cylinder.


I positioned the piston so that it stuck out a little so that it would go into the cylinder


Them put the head of the piston in the cylinder. I lightly tapped the top of the ring compressor to make sure it was flat on the cylinder. Then tap the piston into the cylinder with the wooden handle of a hammer.



All done!

Tom, I spent $148 to have that done. They turned it around and was delivered back to me at the dealership I work at within 1 day. I have used these guys for years, when I worked for LandRover back in the 90's there was an interglactic back order for radiators and those things were taking a dump left and right. These guys were able to handle everything I could send them, kept my loaner cars to within two days use while my customer's cars were down and saved my people a ton of cash on rebuilding the radiators as opposed to replacement.
So when I pulled the cooler off my engine, the first place I thought to send it was Looper Servicenter. When I get my car back from the bodyshop, I will pull the front one and send it there for the same treatment.

Yes thats the way to do it ,when I was doing up T1 motors years ago we didn't have ultrasonic cleaners so it was the cooler in a parts washer or fuel in a tray and re-wash again and again,remember it being amazing what came out.
A lot of people bypass this job .......why

[Amstaff]

Rods are back from JB Racing in Tavares Florida. They look great!
Cleaned and bead blasted
ARP bolts installed
Resized big end
Polished wrist pins
New small end bushings
Back drilled oil holes
Pin fit bushings

As soon as bearings, case gaskets and chains get here I will be able to start on the short block.

[zelrik911]

Very good result.

I am surprised you had to replace the small end bushes with new on your 'young' engine.
Was it done because it was needed, or as insurance because it could be done easily at this stage?

Also, did JB Racing require the big-end shells to resize the big-ends?

I have bought a set of ARP bolts & a spare set of Rods - I just hope they come out as good as yours!

The small end bushings were replaced because I scuffed one up taking it out. I was told it is common to redo the big end when you put ARP rod bolts in. Not sure why but when I know JB Racing is a highly recommended shop that builds a lot of Porsche engines so when they made recommendations I listened.

They did turn out really nice!

[Amstaff]

If by shells you mean bearings to redo the big end, no they did not need them. They were taken back to specs.

[Amstaff]

So I found this spot in the block and after some investigation I found it is fairly common.



The fix?

Next step is to seal the blocks plugs


A bit of scrubbing with a wire brush and then covered with JB Weld

[Amstaff]

I got most of what I need to get the short block put together.

Rod and main bearings, intermediate shaft bearings, both chains and the case gasket set. Once the crank is back from being polished I will start assembly.

[Amstaff]

Well, another hour or so cleaning, another 50 Q-Tips a can of brake cleaner and the case is a little cleaner.

I just have to remember the words of the Master " Patience Grasshopper"

Although I would like to see more progress I have to remember to take my time!





It started to sprinkle a little (for Florida) so I called it a day.

[carrerarsr65]

take your time these projects are a test in patience I'm currently doin a 3.0 twin plug motor heres some pics

[Amstaff]

Looks good! I am trying to resist building the engine too hot to drive around town as a cruiser. I kicked around twin plug, higher compression, wilder cams but I am trying to stick to 9.3 compression, single plug, good valve job, MSD and 964 cams. That should provide plenty of power for the street and yet a good reliable car that I can drive anywhere.

Question for you. Do you soak your new chains in oil before installing or did you just clean them and put them in dry?

[Hammer20001]

Hi Tom... I'm rebuilding a 1986 Carrera and noticed that there is some metal missing in the same spot as depicted in your pic where you used JB Weld to patch...sounds like you did some research on this...what causes this? I'm hesitant to put JB Weld on the inside of the case as I'm not sure how well it will continue to adhere given the heat and oil that the JB Weld will be exposed to.
