Review: I'm rebuilding a 1984 Porsche 944 and tore the motor down last year, and now I'm working on putting it all back together. Plenty of work has gone into this project, and doing the valves was next on the agenda. I first tried the "cheap deal" at Harbor Freight and it's "clamp and compress" design just didn't cut it - the one at Napa did better, but still not good enough - Porsche uses a double-spring on their valves so you need something that does the full clamp. Then I tried the local tool rental places (theirs was a monster - and not designed for reaching into a head), some pawn shops, Pep Boys and finally a place called Performance Auto where I "borrowed" one. That tool almost worked, but damn if it didn't flex, expand, and basically, suck at getting the springs out - it did work, but I knew I'd need something better to put the valves back in once I'm done working on them - so I returned the "borrowed" tool and started digging and found this one. This tool was heavier than the "borrowed" one, but not as insane as the tool rental place had - the one they had would have been ideal for a tractor I think. None of the others I saw, short of spending $120 at Napa would have had a shot at it - and those weren't much different than the borrowed one. This tool really did a great job - and I even made the mistake of putting in 7 of the 8 valves before I realized that I forgot to put in the new valve seals!! This tool make getting the valves back out, putting in the seals and putting them back in a breeze. Does this clamp onto the valves? Kind of - the clamping bit with the handle is more for placement and mlld positioning - the real work happens with the screw bit opposite the handle. What about tool flex? None to speak of. This thing is made of thick metal - about 3/8" thick all around - including the swiveling bars near the handle. It didn't flex at all - and the Porsche springs are some TIGHT springs too - lesser tools were made "bitch" easily by the cylinder head, flexing, warping and otherwise not doing their job, all because of this old Porsche, however, this tool stood strong and pressed on. I strongly recommend this tool for anyone doing work on an engine that needs to push into the heads to remove the valves - this tool makes the job easy. Review: This tool worked awesome to rebuild some Chevrolet small block heads. I found it needed to be well greased on the threads and especially on the swivel that sits on the valve. A couple of hits on the valve springs with a socket and hammer before using this tool made everything go smoothly. Stock valve springs were easy to compress. I used the larger adapter on the springs and it provided lots of room to remove and install the keepers and the valve stem seals. ## Features - OTC's Large Valve Spring Compressor is designed to quickly and easily compress valve springs on overhead valve engines - Includes two valve spring adapters, which fit valve spring retainers up to 1 inch (25 mm) and 1-3/16 inches (30 mm) - Unique, direct action compressor lever gives better visibility of valve spring retainers located in difficult access areas - Jaw opening of 1-3/8 inches to 5-5/8 inches (35 mm to 142 mm); throat clearance of 5-7/8 inches (150 mm) - Durable plated finish; high-grade materials ensure quality performance over the lifetime of the tools ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000F5ECUY | | Best Sellers Rank | #110,402 in Automotive ( See Top 100 in Automotive ) #36 in Car Engine Valve Train Tools | | Brand | OTC | | Customer Reviews | 4.5 4.5 out of 5 stars (961) | | Date First Available | 1 January 2024 | | Item Weight | 2.42 g | | Item model number | 4572 | | Manufacturer | OTC | | Manufacturer Part Number | 4572 | | Model | 4572 | | OEM Part Number | 4572 | | Product Dimensions | 20.83 x 41.91 x 3.81 cm; 2.42 g | | Special Features | Portable | ## Product Details - **Brand:** OTC - **Included components:** 2 valve spring adapters, direct action compressor lever - **Power source:** Manual - **Recommended uses for product:** Compressing valve springs on overhead engines - **Special features:** Portable ## Images ![4572 Large Valve Spring Compressor, black - Image 1](https://m.media-amazon.com/images/I/51cb9byg+yL.jpg) ## Questions & Answers **Q: Valve Train checking spring** A: Tool is not for checking spring. It's for getting spring off of the valve stem. With the head off of the motor. **Q: Does this tool come with a case? Thanks.** A: My tool did not come with a case. **Q: Does anyone know or have you used this on Harley big twinn heads, will it work?** A: As long as the valve is larger than the compression adapter, it should work **Q: Can I use on 65 Pontiac big block 389 cu.in. Heads** A: I can't say for sure, but I've used it on Small Block Chevy, 16 valve Honda, and 32 valve Modular Ford engines. It works great. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***A on 24 June 2013* I'm rebuilding a 1984 Porsche 944 and tore the motor down last year, and now I'm working on putting it all back together.
