         Re:  Federal Income Tax Consequences of the Exchange Offer
              -----------------------------------------------------

Ladies and Gentlemen:

              You have requested our opinion as to certain federal income tax
consequences of the exchange of up to $500,000,000 aggregate principal amount of
newly issued notes of Tenneco Automotive Inc., a Delaware corporation ("Tenneco
Automotive"), for any and all of the $500,000,000 aggregate principal amount of
certain outstanding unregistered notes issued by Tenneco Automotive, which at
the time was known as Tenneco Inc. (the "Exchange Offer"), as described in the
Registration Statement on Form S-4 (Reg. No. 333-93757), filed by Tenneco
Automotive and certain of its subsidiaries with the Securities and Exchange
Commission (the "Registration Statement").

              In rendering our opinion, we have examined and relied upon the
accuracy and completeness of the facts, information, covenants and
representations contained in originals or copies, certified or otherwise
identified to our satisfaction, of the Prospectus filed as part of the
Registration Statement (the "Prospectus"), and such other documents and
representations of representatives of Tenneco Automotive as we have deemed
necessary or appropriate. In our examination we have assumed the genuineness of
all signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such documents. We have also assumed the
transactions related to the Exchange Offer will be consummated as described in
the Prospectus.

              In rendering our opinion, we have considered the applicable
provisions of the Internal Revenue Code of 1986, as amended, proposed, temporary
and final Treasury Regulations promulgated thereunder, pertinent judicial
authorities, interpretive rulings of the Internal Revenue Service and other
authorities as we have considered relevant. We caution that statutes,
regulations, judicial decisions and administrative interpretations are subject
to change at any time and, in some circumstances, with retroactive effect. A
change in the authorities upon which our opinion is based could affect the
conclusions stated herein.

              Based on the foregoing, we are of the opinion that the statements
and legal conclusions contained in the Prospectus under the caption "U.S.
FEDERAL INCOME TAX CONSEQUENCES," to the extent that they constitute matters of
law or legal conclusions, are correct in all material respects. In addition, we
consent to the reference to Jenner & Block in the Prospectus under the caption
"Legal Matters" and "U.S. FEDERAL INCOME TAX CONSEQUENCES" and to the filing of
this opinion as an exhibit to the Registration Statement. In giving this
consent, we do not hereby admit that we are in the category of persons whose
consent is required under Section 7 of the Securities Act of 1933, as amended,
or the rules and regulations of the Securities and Exchange Commission.

              Except as expressly set forth in the Prospectus, we express no
opinion to any party as to the tax consequences, whether federal, state, local
or foreign, of the Exchange Offers or of any transaction related to the Exchange
Offers. This opinion is solely for your benefit and is not to be used,
circulated, quoted or otherwise referred to for any purpose without our express
prior written permission.


                                Very truly yours,


                                /s/ JENNER & BLOCK
