Checking valve seats at home

[Hawaiian Turbo]

I was wondering if you could pour wd-40 in the intakes and exhaust runners to see if the seats are good?

Thanks, Paul

"IF" the heads are off . maybe put some light oil/WD40 in the CC . connect a hose from a shop vac on the port/runner openings and draw a vacuum on it and see what happens . I imagine if it's not sealing well it will draw the oil out of the CC . just a idea .

Yep, heads are off. Actually I poured WD-40 in the CC and after about 5 min. I started to see wetness around the seat.
