I have just done my first ever compression test. This has been warranted by an engine I've been working on that has never given me a good performance...however, I also recently changed the combustion chamber and carburetors and performance was even worse despite several tune-up attempts.
Question:1975 Kombi wrote:Did you have the following?
Did you adjust the valves?
Was the battery fully charged?
Was the engine warmed up?
Did you remove the air filter and hold the flap open?
Were all 4 plugs removed?
Did you do a wet and dry test?
Did you repeat the process and take the average result?
Did you use equal number of compression strokes for each cylinder? I do 6.
What would you pick of this situation (2.0 liter type 4 engine)?
-Engine was not warm... in fact, has not run in about 2 months.
-Prior to parking, valves had been set presumably right.
-Battery fully charged
-no wet test
Tests results:
Cylinder 1: 55
Cylinder 2: 57
Cylinder 3: 60
Cylinder 4: 62.
All this are initial tests.
Rings are all new.
Also, it was my first time to do a compression test.
What I would like to know, may I far much different results if the engine was warm, if I did a wet test? Are those results way too low even for an engine in the described state?? What else may I do before I undertake subsequent tests?
Thanks.
