GMB timing kit is it safe

Featured Replies

I'm hard up for cash and my water pump just let go I found the kit on eBay for $120 I just need to know if I can trust it does anyone know of this brand and advice would help thanks

I have bought and used a GMB water pump in the past with no problems.

I have 4 of their kits in service right now. The only parts of their kit I'll advise again not using is the seals. 1k miles on the valve cover gaskets from one of them and they were leaking worse than before.

Should I get different cam seals or are the ones that come with the kit good

no waterpump change for me, but I just bought a kit with a mitsuboshi belt and all GMB idlers and tensioner - I HOPE it's OK stuff.

 

going in my WRX next month.

I hear ya texan I hate gambling on parts like this I don't want to end up doing a head job in 6 months over a low quality kit

You won't have a problem in 6 months!  The question is whether the GMB parts will last 60K or 105K?  I've been using them but I only have about 25K on the oldest ones that I installed.

 

You should get OEM seals for the crank and cam seals.

My buddy has been using one of the gmb kits for about 25k miles with no issues. My nephew has about 10k on one as well, the other 2 I have installed over the summer so they're still pretty low mileage but I don't forsee any issues.

 

I'd pop for oem cam and crank seals, along with the oil pump o-ring. They really aren't that expensive considering how long they last compared to the cheap ones.

Subaru Seals are a good investment and plan on another t belt change 60K from now to be on the safe side.

That easys my mind and I planed OEM seals and hell if come 60k I'll have the cash for all OEM

Both times that I replaced the timing belt on my Forester the belts were Mitsuboshi. I did the second change only because I was doing the HGs and hadn't done the tensioners and idlers the first time.

 

I think AWD Automotive, where I bought my timing and HG parts said they are OEM.

gumbie stuff is ok but the quality of the materials is lower and the specs they are machined to is looser- thats why they cost less money..... I can say this with 100 percent certainty: Fuji makes a damn good product.

Used a GMB kit with a Subaru WP in my wife's 2003 Legacy and the tensioner failed at 10k. Made an awful tapping sound and the belt skipped one tooth.

 

This also happened to my boss' wife's Legacy almost instantly on a newly installed used 251 shortblock. He thought it was just very bad piston slap, but the belt ended up skipping 3 teeth and the car wouldn't even start due to the cam position sensor picking it up.

 

I've decided to just use the Gates kit with Subaru WP from now on.

I bought this complet kit for my wifes 98 forester one year ago. first the cam seal pop out after 50 miles,then with in 1000 miles the timing belt jumped twice,valve covers leak badly thought maybe I didn't use the right sealent, I would go with the gates kit.also grease was leaking out tensioner bearing.
