Hello,

My name isXXXXX will try to help you.

 

When you change a timing belt what was happen to old belt, like was broken or just millage replacement?

Also check this:

1. Timing belt install correctly. And all marks are align.

2. Verify that the front or rear camshafts did not seize in the cylinder head and then broke free and sheered off the camshaft keyway. If this happens, the camshaft gear will be in time but the camshaft timing will not be correct.

 

Thank you,

Andy

No compression on just one cylinder or all cylinders in this bank?
Ask Your Own Car Question
Customer reply replied 7 years ago
#1 = 0 #3 = 60 #5 = 10 #2 = 40 #4 =25 #6 = 70
Auto Mechanic: Andy, Shop Owner/Mechanic replied 7 years ago

Your compression low on all cylinders you should have around 150-170.

Have you perform a leak down test to see where the cylinder leakage is?

Customer reply replied 7 years ago
Cylinders get flooded, and there is a spark. However I ran the compression test again this time I open the throttle, now it's #1 = 0 #3 = 60 #5 = 30 #2 = 120 #4 =80 #6 = 70.

Your opinion pls.
Auto Mechanic: Andy, Shop Owner/Mechanic replied 7 years ago

Look like either timing belt is off or engine damage, sometime when you put timing belt and release hydraulic tensioner possible timing belt alignment jump. I see that happen specially on dual cam engines, when I do this type of work I always tipple check and spin engine manually to make sure timing marks align each time. If engine was running fine prior to changing timing belt we can assume there mechanically engine fine. So I would look at timing component's first, and alignments, if you need shop manual info on this car just let me know (procedure's, pictures, etc.).

Sorry I wasn't here tonight earlier but I will look for your messages and try get you information asap.

Also I usually pull fuel pump fuse or relay out so cylinders doesn't get flooded.

 

Thank you,

Andy

I pull entire instruction for removal and installation this is off the shop manual, look on instructions for Millenia since there is also information for 626. This is for 2001 Mazda Millenia V6 2.5L P, there also S model if you need one for S model please let me know. Also if you have any questions just ask, I will be working next few day's late in shop, I have to rebuilt 2 engines but I will check site during a day and will try to get back asap.

 

Thank you,

Hi Andy,

 

I did a leak down test, all valves are opening and closing when they should.

When the timing marks are set, should the markings on the two gears inside the head also be aligned?

Auto Mechanic: Andy, Shop Owner/Mechanic replied 7 years ago

Timing marks should be aligned like on Fig 3, marks inside a head usually technological for factory only, but let me take a look in head exploded views for this one if any info I will posted for you. If you on all timing marks as figure 3, I would spin engine manually and check if marks aligned each time.

 

Ask Your Own Car Question
Auto Mechanic: Andy, Shop Owner/Mechanic replied 7 years ago

I verify, on this engine inner marks have to be aligned together prior timing belt installation, only if camshafts was removed, like if you was doing head gasket. But check when engine on timing marks as per figure 3 the inner cam marks have to be together as well. If camshaft wasn't removed you shouldn't have to align them, but if cam sprockets for example move free like I mentioned in my first post, this marks may not be align together. Here are some information for Camshafts removal installation, this may help you toographicgraphicgraphicgraphicgraphicgraphicgraphicgraphic.

 

Thank you,

Andy

Andy,

 

Thanks for the information I found one intake valve in the #1 cylinder stuck open which would explain the 0 compression in #1 cylinder. So I removed both heads and sent them to the machine shop for overhaul. Please advise!

Auto Mechanic: Andy, Shop Owner/Mechanic replied 7 years ago

yes this will cause problem with compression, when you get heads back just follow instructions I will look manual for all torque specs and any info you will need to put heads back. Sorry I was working in shop for last 2 days very late and can't get to the site. I will post all information for you tonight or tomorrow.

 

Thank you,

Andy
