Let me start of saying this is my second CSC. The first one was a 1995 LQ1 and my current one is a 1994 LQ1. Purchased the '94 back in November 2017, and been slowly working on bringing it back to a healthy life. A few stats about it the car: - 1994 (build date is march of 1994) - LQ1 3.4L DOHC v6, 4 speed - Red body, Black interior, White top - 93,xxx miles - VIN 1G3WT35XORD377734 I trailered it from Nebraska to Kentucky in December while my plant was closed for holiday shutdown. Couldn't drive it as it was a garage queen and knew it need some work. Current progress on the car has been a total top end reseal on all gaskets including the dreaded oil pump drive seal. The Head gasket wasn't leaking but the fire ring on cylinder 4 was starting to bulge into the cylinder. So I went ahead and took the heads off and sent them to a machinist and had them check the heads, put new valve stem seals on, and resurface the gasket mating surface. Other things I've done was chased a fluctuating idle which ended up being a chewed up fuel pressure regulator vac line. Fixed other harness wires from mice damage, including cyl. 3 & 5 injector wires, and oxygen sensor wires, it wasn't bad damage just annoying. I've also replaced the original red and black plug wires, coils, ICM, water pump that had shaft play and noisy bearing, oil pump drive shaft, oil pressure sensor. I've also pulled all lifters out making sure I marked their loaction and let them soak for a week in Berrymans B12 chemtool, and then let 1 week in marvel mystery oil in hopes they would be "refreshed". I'm currently in process of putting it all back together. So far I've got both cylinder heads on and torqued down. Exhaust manifolds put on, rear head cam carrier on and torqued down. New timing belt idlers on, new plug wires routed to factory look. I also ported and polished the lower intake manifold, but it's too time consuming for too little gain so that's all I did with that. I'm waiting on a new timing belt actuator from group1autopart.com to finish up the engine. I've got a list of things needed to be done and a couple boxes full of parts to put on so it'll be road worthy but I will update as I finish things. f5e8c930aba0e937e242334eec673d48.jpg53691bc38b7dbfd961c4736e501937c3.jpgef4ae67c4dd6f728a32d76904612597e.jpg2699d2970cf5bf7066e97ca31b991bfb.jpg6d2af34e7aaa4b398322f40ac2efb1c1.jpgec46f65048e88a2283aee41c507bd5ec.jpgd955d0a4512bcdff6a530d1d06bd00b3.jpg34be5343af9430109da293253cf8a30f.jpg6b80b52228f333ffb20f2391ba792bd1.jpg Sent from my SAMSUNG-SM-G930A using Tapatalk

I received my timing belt actuator today. However the brass bushing is stuck on the old one, and I called the dealership to see if the mounting plate with the bushing was available... Which it is unobtainium. Does anyone have one for sale, or have a way to remove said stuck bushing and put on the new one? Sent from my SAMSUNG-SM-G930A using Tapatalk

Wait...the brass bushing is stuck to the old actuator, preventing you from removing the actuator from the bushing?

Yep, I done stabbed myself trying to pry it off the old actuator too 4561d6d1ac7ffb9ee6972e93cdfaa71b.jpg Sent from my SAMSUNG-SM-G930A using Tapatalk

Spray the daylights out of it with penetrating oil?

Put in in a pot of boiling water?  Brass and aluminum have differing rates of expansion...the heat may allow it to loosen a bit without damaging the bushing...

 

It might work, not sure, but might be worth a try.

I'd do penetrating oil and heat. Heat the brass fast and evenly and when a little spit on the tip of your finger sizzles when you touch it pry evenly with 2 screwdrivers.

do you have a propane torch?

 

a well directed conservative amount of heat only on the bushing should expand it enough to free it from the aluminum actuator, brass expands faster than aluminum does.

 

Before you buttoned up the block did you apply any assembly lube to the intermediate shaft/oil pump gear drive? I notice in that photo you took both are quite dry.

I can buy one and try that. And when I took the Oil Pump drive shaft out and replaced it I put some fresh oil on it, and the gear and then I took my mini impact and spun the Oil Pump and got some oil moving. I'm gonna prime the Oil throughout the engine before I crank it up too Sent from my SAMSUNG-SM-G930A using Tapatalk

Clamp it in a vice and set two screwdrivers or similar up on it first. Have to be fast when you sweat stuff so you get it before the aluminum expands too or let it cool and start over.

Got the bushing off the old actuator however I ripped the boot on the old actuator, so having a spare will be buying another new one. But I used the torch and heated the bushing. I couldn't get it to slide off so I had to pull out the adjustable pliers and twist it off... That worked but it now has some small knicks in the bushing, even with covering it with a rag. But I did my best with the dremmel to smooth them out. I also had to heat it up and tap it on the new actuator. Sent from my SAMSUNG-SM-G930A using Tapatalk

I might still have a hosed actuator with a good boot, and if so, I also should have with it the used actuator mounting plate, and bushing..I’ll do a little digging.

So to time this engine, the #1 cylinder is at TDC. (All factory marks are visible in yellow paint too btw) The Rear bank cams need the flats to face up, while the front bank cams need to be 180º out and facing down correct? I have the Kent moore kit too but I can't get to cam cog bolts to loosen up. And I'm not making sense of this Chilton manual I have. Sent from my SAMSUNG-SM-G930A using Tapatalk

On my LQ1, I found the timing mark on the harmonic balancer to be off by approximately 6 degrees. I used a wooden dowel inserted into the Plug hole for #1 to find TDC. There’s a little more to it, but it’s not difficult. Are you having issues with the bolts, or getting the gears loose on the cams?
