Engine Removal Update

[Jeasen]

I thought I would give everyone an update in regards to my engine rebuild. My block, old pistons and rods, and new forged pistons are sitting at the machine shop waiting for their turn. The number one cylinder will be sleeved and the the block will be bored .040 over. They thought maybe some time this month for the machine work so I am waiting patiently.

The crank has been turned .010 on both the mains and rods and checks out good. I ordered new main and rod bearings and have them in hand. I want to start ordering other parts that I need so when the block is done I can immediately start the assembly process.

I have a question about harmonic balancers. The one I removed (with the timing mark 18* off) did not have any balance holes drilled in it. I went to Rock Auto's site and they have four choices listed for a 1992 Typhoon. Three of them are symmetrical like the one I removed from my motor. l The fourth one has balance holes drilled in the outer ring. When looking at the back side outer ring with the keyway at 12 o'clock there are extra holes dilled from about 1 o'clock to 4 o'clock. It seems like the one with the extra holes drilled would be the correct one to use since the motor is externally balanced. Does any one have a stock harmonic balancer laying around that they could check for me?

I also need to order piston rings. I talked to Hastings Tech Support and they recommended their moly rings. They said they would work great in a turbo charged application. Since I am building a street motor and will be using the stock turbo I tend to agree with them. Any suggestions other wise?

I know I will have more questions as I go on. Thanks in advance for your help.

Hey Jeasen,

The plasma moly is sprayed into a groove that they cut into the top ring. It can be applied on many different types of material. I would recommend a ductile iron or stainless top ring, they will hold up to boost better than a cast ring. I am surprised your new forged pistons didn't come with a ring package.

Check with Prop Top, I'm sure he has a balancer laying around that he can look at.

Good luck with your project.

Gents,
I just happened to jump on here. Pics are attached as requested. Not sure of the question but the one still on the motor is out of my Syclone. The other one was from a Typhoon. I have another one somewhere that we drove all the weights out of and used it for an Internal balance job on the Little/Stock build motor. Hope this helps.
Thanks,
Bob

Jeasen,
Pay the shipping and you can have the one off of the Typhoon motor. I will have to check and see if there is any signs of slippage but I don't believe there is. just let me know. Pioneer also make one not sure of the part number.

I checked mine and it is the same part# as your Typhoon one. When comparing the two it is obvious that mine has slipped also my timing mark was about 18* off of TDC. I would be glad to pay the shipping just let me know how you want to handle the payment. Thank you, Jeasen

Well my block is back from the machine shop. The block has been bored .040 over and a sleeve has been installed in the number one cylinder. The block has been cleaned and is assembly ready.

The rotating assembly is back from the balancing shop and I had them install my new pistons on the rods.

I have started assembling the short block as time allows. I know that this is going to be a slow process since it has been a while since I have done this. I figure that I would just take my time doing this, double check the things that I do and enjoy the process.

I would like any advice anyone has to offer that will help make this a better build.
