Bought a car for FE but im having trouble need Mech help!!!

[Tepco]

I posted this exact question on other sites with mixed answers, so i would like to try it here. The car got 36mpg on the first 1/2 tank. Now im driving more efficiently but my mpg is dropping.

Please take a gander and tell me what you think.

My question is my 1989 Civic HB D15b2 that is smoking when i rev it or excellerate hard. Its burning about 1/2 Qt every 200 miles. It's leaking from the dist the normal amount.

Here is some engine info.

I just purchased it for a commuter, it was a one owner daily driver, it has 217k. i bought it with a seized cam. i replaced the head with a head off of a 1993 DX with between 100-150K, and had it milled and torqued to the TSB specs and all new gaskets, the cylinders still had cross hatch marks on them. ( i didnt talk to the owner so i dont know the full history of the engine)

New timing belt, water pump, plugs, PCV valve.

Starts and runs great and as strong as i would think a 1.5 could be.

Dry compression check showed, from dist. to timing belt:

180 185 170 180

Leak Down

4% 4% 5% 4%

The car appeared to be running for quite some time with a leaking head gasket. When i replaced the PCV valve i noticed a build up of carboned oil on the hose connecting the PCV valve, although air flowed through the line fairly easily.

I hate posts that lack info so i hope i listed enough.

Please let me know what else i could check or what else it may be.

Thanks,
Tim
