I did the leakdown test today. I got a shitty one from harbor freight. At first when I hooked it up I couldnt get the guage to get to zero. it was around 30%, then I realized that it was leaking between the tester and the spark plug hose adaptor.
Once I held those to parts together and got it down to zero. It didnt really show any leakage. I could hear a little comeing from the dip stick tube, but that was it.
I let it warm up first, watching everything carefully. The top rad hose and pressure in it, the overflow was raising slowly. Then once the MS guage read around 190, and the stock guage was around 1/4, the overflow filled up faster. Then the stock guage jumped from 1/4 to just over 1/2 for a second then up to hot and started dinging. I shut it off the coolant was boiling into the overflow and MS guage rose to around 207 then went down
So I don’t know what else to check. Any one from Hybrid want to PM me with a estimated quote on how much it would be to fix my problem?
