    So I've currently got a smokey Civic Type-R engine apart in the garage.

    Before I took the engine apart I did a compression test and a leak down test on it.

    Compression test results showed that all four cylinders had good compression ( around about 190PSI) and it was also positive to see that the compression was consistent across all four cylinders. The leak down test was also good, showing very little leakage. This all pointed to a problem with the head.

    So I decided to take the whole thing apart anyhow.

    Engine mounted on a stand:-

    Crank pulley bolt being removed :-

    The pulley bolts comes off so much easier with the engine out of the car.

    Timing belt being removed :-

    The engine looks like its been maintained no slugey deposit on the head... check the valves, piston rings and bore to see what going on. If you have oily piston crowns that will be the first tell take sign its seeping in..Hairline fracture on the head is one possiility.

    He hasn't been running that engie with too much oil has he?

    Head removed, straight away you can see the problem, piston tops full oil, more on the exhaust side
    20140529_210917.

    Lots of oil present, where there should be none.

    Bores are all good though, smooth, no scraping or scuffing marks. Pistons are nice and tight, no free movement, indicating good rings, gudgeon pins and shell bearings
    20140529_211000.

    Turning the crank over, everything moves nice and smooth, no noise etc. So bottom end is all good.

    Time to look at the head

    20140529_211355.

    There you go !! Seepage from exhaust valve stems.
    20140529_211408.

    20140529_211422.

    So this head needs to be reconditioned (new valve stem seals put in etc) or a replacement head sourced.

    valve stems for sure , why people buy performance car and put shitty oil filters like fram just to save a few pence..that engine needs oil to Honda standards.

    strange to see all the exhaust valves black with oil.
