TOD after waterpump failure and Timing Belt change

[Bizangous]

I have a 92 Loyale with 160k. A while back my waterpump failed. I get it towed home to replace the WP and decide to do the timing belts a the same time. Now I have it all back together and running but I have a very lound tick coming from the engine. It sounds like the TOD noise i get sometimes but louder. It seems to come from the center of the engine but I can't really pin it down.

 

My question is could my timing be off causing this tick? I drove it around the block and notice no hesitation or different feeling in the power and driving of the car only the tick. I also turned the crank pulley by hand and the timing marks are lining up as the should. Right now I afraid of running it any more and causing and engine damage.

did the engine overheat?

 

Is it a hollow deep kind of sound?

 

Are you sure its not a tensioner or idler for the timing belt?

I don't think it overheated. I never saw the temp gauge go above normal and it was below freezing when it broke down. I replaced the idler pulley and both tensioners with the T-belts. The noise sounds like a loud distinct tick and it speeds and slows with the engine speed.

typically this is the EA82/ER27 oil pump needing resealed. the suction port side of the gasket between the block and pump gets compromised.

 

why now after this work though doesn't make sense so who knows. "center of engine" doens't sound good.

I think I solved the problem. I added some Marvels Mystery Oil to the crank case and ran it until it warmed. The noise diminished than vanished. A stuck hydraulic lifter? It was much louder than I had ever heard coming from my subie before so it scared the crap out of me initially. I hope that is all it was.
