The exhaust manifold often warps and cracks, breaking off the studs between the cylinder head and the exhaust manifold. A ticking type noise may be noted most noticeable when the engine is cold.

same prom, replace all rusted bolts and seals, that in turn restored lost power and gave me better fuel consumption.

I bought this Villager used 3 years ago, with about 130,000 miles on it. There was always a rattle when cold; I still think that may be the lifters, but at about 160,000 miles I developed a distinct exhaust leak. When I checked the exhaust manifold (rear side)I saw that four of the six studs had rusted & broken off. I dunno how long it was like that, but I'm sure they didn't all go at the same time; I'm amazed it held up this long. Now I have to decide whether it's worth it to repair the head, or just scrap it for $300.
BTW; all four original tires blew out on me, one-at-a-time over the first year. They were new when I bought the car, but had NO manufacturer info on them anywhere. I advise checking tires carefully if buying from a budget used-car dealer. (Especially "Woodbridge Auto Auction" in VA.)
Engine ticks when cold. It seems to seal itself after the engine gets warm, but there is a noticeable loss of power, especially on hills. Have not tried to fix et. Dealer said it could be done by rebuilding the heads for $1500.
