As usual, good news and bad news. Good news is I started tear down and thought for a while I had a bad timing belt tensioner, rock in my alternator or engine knock. Had it ever since we did the Buffalo Scooby Canandaigua lake cruise. I checked for knock by logging and found nothing and figured I would find it when I started tear down this spring.

Usually when I put my hand on my alternator cover, the metal on metal sound would stop. This is why I thought it was something with the alternator.

Cover I am talking about


I just got started taking things apart. Went to take off the alternator cover and one of the bolts was loose. Looked on the back and found this.


Font shows signs of it moving as well, the red residue


I decided to start the car and what do you know, metal on metal sound is gone! Woot, 1 problem down.

Now the bad news. I have to pull a ton of **** out of the engine bay to get to the water pump. This is going to be more involved than I thought.. Hence why I am starting 2 months before my tune.. At least I have a garage of my own to work in now.

Done for tonight. I need a socket big enough to take off the crank pulley. Ill pick one up tomorrow so I can keep going.




Question for anyone that knows.. Is this wear normal on the timing belt? I cant recall if my other one was worn like this or not. Only about 10k miles on it. Ill investigate more after I get the crank pulley off and the rest of the timing cover


PS, having a smartphone with the photobucket app is really nice..

Pulled the crank pulley and timing cover and found my issue with the timing belt (that I didnt know I had until last night.)

The belt guide is rubbing. But it isnt touching now. Thoughts on causes? I am thinking a bad tensioner? Would you replace the timing belt?




Appears to be touching the very middle and the sides. Per the shiney parts.




I checked my old timing belt that was run for a couple thousand miles (about a year). It also has the marks, but not as severe.


Also think I spotted my coolant leak. Water pump is going to have to come off, which means I have to pull the timing belt.. blah..

Im really leaning towards a bad tensioner. If the crank pulley turns clockwise when running, why else would the belt be jumping up to touch the belt guide?

So apparently the timing belt guide is adjustable and you are supposed to have it x distance from the timing belt. You'd think with all the time I have in this motor, I would have known that and not just slapped it on.



Holding off on ordering parts until I finish my teardown job. I only have to removing the timing belt, tensioner and water pump to verify where my leak is coming from. Once I get the pump off, that will determine if I need a new pump or just a new gasket.

On the list so far:
Gates timing belt
Gates AC, power stearing and alternator belts
Gates tensioner
Right stuff gasket sealer
Possible new water pump
water pump gasket
new timing belt guide

Think I will get all that back together, make sure all is well and it works and then tackle the new header.

Think I found my leak.


Pointed out by the screwdriver


Gasket appears to be a little beat up here




Also, REALLY glad I pulled the timing cover and caught this before it got ugly

Decided to order a bunch of crap at the same time. Much cheaper than the dealer on Amazon.

Gates timing belt
Gates AC, power stearing and alternator belts
Gates tensioner
Right stuff gasket sealer
New Gates water pump, includes new gaskets
One idler pulley as it appeared a bit crunchy
SEM trim paint - going to paint all the yellow in the bay black

Make sure to put it together right this time and hopefully that will solve all my little issues.

Ugh. While pulling the stock header off.. I found some oil and thought my head gasket was going. I did a little more searching and found the oil appears to be coming from the oil return line.

Gates water pump is here. I find it interesting that they include a felt/fabric type gasket, where-as the stock gasket is metal. I plan to use gasket sealer without, but still wonder why the difference. Cost?

Got the car put back together today with the nice weather. Luckily work was lite and I was able to ditch early to get started. New water pump on with a stock gasket. Timing belt back on and installed the header.

Put everything back together and it fired.. woot! About 90% there. Still burping coolant and quit for the night as to not bug the neighbors.


The header install went smooth for the most part. It is a bit tight fitting. The bolt holes are a little smaller now from the Swaintech white lightning. Also had a little trouble lining up the top bolt to the Perrin up pipe, but was able to get it done.

Once installed and everything back together I ran it for a bit and spotted smoke pouring out of the slip joint. I used never seize to put it back together and line everything up. I think it is just burning off. I am going to keep an eye on it a bit longer to see if it is a leak or not.

Sound: Sounds just like the stock header. My car sounds nearly exactly the same as it did before the tear down. I took a before video of the car and will do an after soon. I want to get the tune done and record it on the dyno so you can hear the exhaust outside the car at idle and WOT to see if there is a difference.


So, as of right now, I am satisfied that I didn't screw up the timing belt. I made sure my guides all had enough space and checked, rechecked and checked again on the timing marks.

I only had one CEL and that was because I forgot to plug in the front o2 sensor. Plugged that in and cleared the code and it didnt come back.

Ill pick up again this weekend. I still have to adjust my bumper cover a bit and I want to take it around the block to check for any leaks and log it.

I ran the car for about 20-30 minutes today to check for leaks. Doesnt appear to be any coolant leaks. Also, it appears my concerns about the header slip joint were nothing. The smoke stopped after a while. I am pretty sure it was just never seize burning off. It def doesnt smell like exhaust and I cant feel any leaks at any of the gasket or the slip joint, so I hope I am good.

I have an oil leak to fix from the oil return under the turbo. Also going to check it for boost leaks since I had the FMIC piping apart.

Sent an email to EFI logics to add smoke testing the intake before my tune. Hopefully that will cover all the bases.

New Tune vs the tune in Post 2. Only changes were swapping the Hallman MBC for a Grimmspeed EBCS and swapping stock header for the Litespeed.
**Waiting for EFI to update their dyno database for better graphs. This is what I have for now.

Chris updated the dyno database. Some comparisons

Looks like I hit my goal. I wanted to get a similar torque line to Dave/Chinky's build as he always had more torque than I. He ran a Maddad UEL header. His car in blue, mine in red


Comparison of all 3. My previous/stock header tune in Red, Chinky's in blue, my new/UEL header tune in Green


And one more, old setup vs new setup - litespeed header works!

Car is away for storage and I started a new project. Cleaning up the engine bay and getting ready for a speed density tune in hopes of improving drive-ability. Here is what I have going on so far. Prepare for photobomb..

Tear down starts


What a mess




Parts to be powder coated


Parts started rolling in








Also picked up my intercooling pipe from the welder with the new 3/8bumg for the IAT sensor. I dropped it right off at the powder coater and they said it should be done next week sometime.

Also got my Moroso AOS yesterday. I'm modifying this with some larger hose and getting some black fittings to replace the copper.




New parts came in while the baby was coming. Mishimoto BPV return line. Came in a kit and il will be selling the others as they are for an STI with a tmic.


1/2in connections for the AOS.


My 1/2 barbs came in for the Moroso AOS


Vs the 3/8 brass fitting


Also got the JDM BPV today. I still have to polish it. Picked up those supplies last night. It should look pretty good when done!


Mocked up with the APS hose, Mishimoto return hose and stainless hardware.


After

Quick pic to show how corroded some parts were.


Stainless hardware from belmetric is here. This is my weekend project so far. Lots of work went into getting these clean.

More updates to come as I move along!
