If it is expected then would this car be rather tested with two-level tester where coolant would be less likely to enter the second stage? Wear goggles, heat resistant gloves and outer clothing that will protect you from burns if coolant system fails during test. The cylinder head tester shows whether there is carbon dioxide (CO2) in the cooling water of vehicles with gasoline, diesel and gas engines. The mayo stuff on the dipstick or cap doesn't always mean head gasket failure, it could just be condensation. Just plug the tool into the radiator cap and pour a small amount of the indicator liquid into the tool.

Block tester Kit detects exhaust gases in the radiator and so checks for gasket damage, cracked or warped cylinder head. there will always be a debate on what parts of a blown gasket this will detect and always debates on test fluid type / colour. There are so many faults that can affect the compression test results, and so many types of HGF that won't affect it, that I don't think a compression test is a very reliable way to detect HGF. It can be used to connect the piston with rings, and also helps to secure the piston to the engine body. The pump is crucial in detecting small leaks, atomizer helps to dissolve more gas in the test fluid.Rear crankshaft rear oil seal replacement tool for Iveco, Fiat Ducato, Peugeot Boxer, Citroen Jumper 3.

I spoke to a second garage (an MG specialist) who said testing emissions to determine whether the head gasket had gone was worthless and they never do it. Start the engine (preferably when it is warm), increase the speed to obtain a higher combustion pressure.

The cylinder head leak tester has a conical stopper that is placed directly on the cooling water expansion tank.
