22re timing chain dilemna

I know this has been discussed many times but what will one more hurt.92 4runner, bought last fall with 175,ooo miles, has about 185 now. Ithad a little timing chain noise when I bought it, but it wasnt a bigconcern to me. My 86 has gone 290K with no trouble. Well recently the92 starting losing antifreeze, I have noticed some white exhaust smokeat startup and there doesnt appear to be any antifreeze in the oil. So,this means head gasket, right? or could it be the TC causing this?would it be absolutely foolish of me to have the HG fixed and not havetht timing chain done at the same time? It will bascially cost medouble to have both done, not an expense that I relish right now. But Irelish the thought of paying that same amount in 3 months, on top ofthe HG repair now, if I dont do it all at once. Common sense tells meto bite the bullet nd do it all now, but I just want to make sure.....

Basically what it takes to inspect the chain is pulling the valve cover. Once the valve cover is off the chain is exposed, about 3" worth or so. You can turn the crank with a breaker bar to move the chain for a "complete" inspection.

I DON'T know if you'll be able to check for stretch. I would imagine grabbing the chain and trying to pull it upward might work, but there may be some inherent slack (perhaps why we have tensioners?)
