OK, finally Calvan has released their version of the OTC 303-1203. The Calvan is pictured on the left and the Rotunda is on the right. Calvan actually did a very nice job, improving on the Ford design and including a storage case. And they even upgraded the thread tap by adding badly needed length to it to reach down in the spark plug recess of the cylinder head. Still no word about if Calvan is going to tackle the production of a lower cost equivalent to the 303-1398 porcelain remover. We can special order the 303-1398, but with the price around $700 we have refused to stock them.

Hopefully someone will figure out an easier, less expensive way to remove the porcelain without the over-priced Rotunda 303-1398. Early TSB’s from Ford said to remove the porcelain with needle nose vice grips. I’ve also talked to tech’s that chip away at the porcelain until it can be removed piece by piece. Mustangs, F150’s, Vans and Rv’s are affected, any Ford with a 4.6 or 5.4 could have this problem. If anyone has found an effective way to remove the porcelain, please comment. At least now we have a nice alternative in the Calvan 39100 to the Rotunda 303-1203.
