Parts store spark plug thread repair failed!

Ford Problems No Comments

The most common problem we help people deal with is related to parts store thread repair kits that have failed. Once this happens the owner or shop sometimes tries unsuccessfully to re-install another of the same type inserts. When a parts store insert fails it makes the hole bigger, which prevents the same size insert from being able to help matters. Other times, some shops will say (mistakenly) that the cylinder head has to be replaced! If you have a similar situation, we can most likely recommend to you or your repair shop a professional, permanent type repair that will save the head and save a lot of money. No time to read?

Kent Moore No Comments

Kent Moore J-42385-507DennisB © Summary: Kent Moore inserts always available with us. We have the Kent Moore J-42385-507 head bolt inserts in STOCK. They are frequently on backorder with GM but we keep plenty in stock. See the following link J-42385-507 or order by phone at 800-524-9783. The inserts are commonly used on GM Northstar and some other applications when an M11x1.5 Kent Moore thread repair kits is used.

The inserts are held in by the bottom being expanded when the install driver is used. This creates a solid repair and is GM’s only authorized thread repair. GM does not recommend stud type repairs in place of the TTY (Torque to Yield) bolts. Ten inserts are used per side so if doing an entire block be sure to order 20. Some GM dealers prefer to order these in bulk at an even greater savings. See our bulk pricing on the Kent Moore J-42385-507 100-Pack.

Broke a 3/16″ Drill Bit – What to use

How To Auto Repair, TIME-SERT Kits No Comments

Rescue Bit use DennisB © Summary: This is another question regarding how to drill out a tool like a drill bit which has a hard metal compound. While the Rescue Bit can also break in some cases, it has saved a lot of jobs. The success rate is good if recommendations are followed and common sense prevails.

Question – I broke a 3/16″ drill bit trying to drill out a broke bolt. Should I use your 1/8″ bit? The broken bit is about 1/4″ inside the hole with jagged edges showing, will the rescue bit be able to get the bit out, then the remnants of the bolt? Should I just use an extractor to get the bolt after the rescue bit removes the broken drill bit?

Answer – Usually you go a little smaller than what you’re trying to drill out so you can use a rounding motion, so I’d try the 1/8″. The rounding motion makes the hole a little bigger to reduce binding which could break the Rescue Bit. I’d also start with the reamer end of the Rescue Bit, because it would have less chance of snagging and breaking on the jagged part of the broken drill bit. An extractor could work but as always be careful not to break it! Too much force will break an extractor every-time if the bolt won’t budge. If the extractor idea doesn’t work keep in mind we sell Time Sert thread repair kits that can be used if needed to install a solid inert that allows the use of the same size bolt. Just need to know what size bolt to recommend a kit. In most cases we have over-size kits available, if needed that still uses the original size bolt.

The 1/8″ Rescue Bit can be used in a drill or in a die grinder. We have the 1/8″ Rescue Bit listed with a collet which is the adapter that fits 1/4″ straight and 90 degree air die grinders. It adapts the die grinder so it can use 1/8 accessories, in this case the 1/8″ Rescue Bit. See our Rescue Bits for sale on our main website.

Calvan 38900 Review – 2002 Ford 6.8 Liter V10

Calvan Tools, Consumer, Ford Problems No Comments

Ford sparkplug blowoutHello Dennis, Good morning.

Hope you’ve had a great summer so far. Quick update for you.  I took on the project to install sleeves on all the spark plugs on my V-10 F-250.  I had originally installed two sleeves (of lesser quality) and found out that the previous owners had also done another one (of lesser quality also).  In all, three spark plugs had blown out of this engine before I decided to replace them all.  I ordered your Calvan 38900 Ford spark plug thread repair kit and four extra sleeves (inserts) and started working on my truck the last week.

F250 Sparkplug blowout problem
DennisB © Summary: Here’s a common question we get when it comes to Ford spark plug blowouts and which kit to use on 2001 and up Ford RF-1L2E Romeo style heads.

Then there’s the issue with parts store kit like the Helocoil Save-A-Thread kit that commonly fail making the hole bigger, which requires an oversize repair kit. We deal with this all the time. The heads can be saved in most cases if done properly with a good quality kit like the ones we sell.

Calvan 38900 Videos – Ford Spark Plug Thread Repair

Calvan Tools, TIME-SERT Kits No Comments

Calvan 38900 Romeo

DennisB © Summary: We’ve compiled some of the Calvan 38900 spark plug thread repair videos here. Some are from which is our second website. We’ve been selling spark plug thread repairs since 2005. Calvan 38900 is the 2V kit which is used on many 4.6, 5.4 and 6.8 Liter engines made by Ford. The common spark plug blowout issue has been around quite awhile and surprisingly the issue still persists. Ford starting using the 3V engines in 2004 on some models. The 3V engine uses an M16x1.5 spark plug that doesn’t have the same blowout issue as the previous M14x1.25 spark plugs used in the 2V engines. The 3V spark plugs have a breaking issue when removing. The threads can be damaged though which could indirectly cause a blowout issue if the threads are damaged when changing the plugs. What people don’t realize is that Ford still used the 2V engines that have the common spark plug blowout problem after 2004 in some models. One surprising fact is that the 2V engine was used in the E150 with a 4.6 from 1997 all the way through 2014! See our Calvan 38900 product listing for a full list of vehicles that uses the 2V engine.
