Clunking during startup?
A heavy clunking is coming from the engine area while it is starting up. Actually, it is only while the engine is just firing up, meaning after the starter is engaged, but before it is firing on all cylinders smoothly. Just during the time the engine is bucking to life. about 1-2 seconds long.
The clunking is just like as if a engine mount is broke. Or like a exhaust manifold is hitting the firewall.
But 3 mechanics had ID'd the existance of the sound, and OK's all suspect parts that may cause the clunking.
Any ideas??
I am replacing the <gone> upper arm bushings in a few weeks, but is the frame bucking that much to clunk around an upper arm?
Thanks guys......

It might be a motor mount...
At a low speed, with first gear held on, accelerate fairly briskly, then let off the throttle just as briskly. Did it clunk when you first accelerated </B>and</b> when you let up on the throttle? If so, then I'd say it's a motor mount.
Could it be the timing chain? I can't hear it on my Aerostar, but on my Nissan it makes an audible clanking sound for a few seconds...this is when it adjusts, they tell me.
