Fair price for this solid upgrade. I had my timing chain done and threw this timing chain guide bolt/plug in as well. It installs beautifully, is nice and heavy which should make that promised limited lifetime warranty not an exaggeration. It feels good to know the upper timing chain guide bolt will never break and cause me annoyance and expenses.
I didn't have issues with the timing chain, but wanted the new sprockets, tensioner and this "plugbolt" to avoid all proven Ecotec timing chain issues. My LE5 2.4l Ecotec in a 2008 Chevy HHR had 150'000km/~93'000 Miles and problems often arise on first gen timing components after/as of 100'000 miles. if you're getting the chain done, get this bolt! If your original upper guide bolt broke, you're saving hundreds in labour by getting this and its a "No Brainer".
With the newest timing components and this bolt by "Dorman" I feel confident that the timing chain will not be an issue in the future anymore and I can drive drive drive without worries and the second timing chain job will have a waaay longer interval before I consider it being in need of renewing. Awesome!
Never would have learned about the bolt without ZZP having it in the catalogue. I live in Germany and "Dorman" isn't known here. The Ecotec 2.0, 2.2 and 2.4 aren't in many cars over here compared to the US, so mechanics aren't savvy to the issue. With shipping I paid around 45$ and I was glad to pay intl. shipping for this. Thats how important it is for those engines and as an "insurance fee" it is nothing.. It ensures the engine's longevity.. I glady payed Fed Ex too much money to ship a little bolt to me. Thanks for having the product in the Catalogue ZZP!!! Thanks to you one of the ~3000 Chevy HHRs in Europe will not get an issue with that breaking bolt problem :)
Mount with 90nm like the original plug. This replaces bolt and plug. It's a 2 in 1 and simply genius. Why GM hasn't made this the new standard for new timing chain components to those engines baffles me..
